The requirement for zebra to be ready to accept connections is a generic problem that is not
specific to bgpd. Making the script to wait for zebra socket a separate script and let bgpd and
staticd to wait for zebra socket.

Recent changes brought l2 vlan concept which do not have DHCP
clients behind them and so DHCP relay is not required. Also,
dhcpmon fails to launch on those vlans as their interfaces
lack IP addresses. This PR limit launch of both DHCP relay
and dhcpmon to L3 vlans only.

- Support for non-template based FRR configurations (BGP, route-map, OSPF, static route..etc) using config DB schema.
- Support for save & restore - Jinja template based config-DB data read and apply to FRR during startup
**- How I did it**
- add frrcfgd service
- when frr_mgmg_framework_config is set, frrcfgd starts in bgp container
- when user changed the BGP or other related table entries in config DB, frrcfgd will run corresponding VTYSH commands to program on FRR.
- add jinja template to generate FRR config file to be used by FRR daemons while bgp container restarted
**- How to verify it**
1. Add/delete data on config DB and then run VTYSH "show running-config" command to check if FRR configuration changed.
1. Restart bgp container and check if generated FRR config file is correct and run VTYSH "show running-config" command to check if FRR configuration is consistent with attributes in config DB

Ledd is the last daemon that is not enabled to run in python3.
Even though there is a plan to deprecate this daemon and to replace it by something else it's one simple step toward python2 deprecation.
**- How I did it**
Changed the `command=` line for `ledd` in the `supervisord` configuration of `pmon`.
Copied what was done for other daemons.
**- How to verify it**
Booting a product that has a `led_control.py` should now show the ledd running in python3.
I ran `python3 -m pylint` on all `led_control.py` plugin which means that most of them should be python3 compliant.
There is however still a risk that some might not work.
- Why I did it
Initially, we used Monit to monitor critical processes in each container. If one of critical processes was not running
or crashed due to some reasons, then Monit will write an alerting message into syslog periodically. If we add a new process
in a container, the corresponding Monti configuration file will also need to update. It is a little hard for maintenance.
Currently we employed event listener of Supervisod to do this monitoring. Since processes in each container are managed by
Supervisord, we can only focus on the logic of monitoring.
- How I did it
We borrowed the event listener of Supervisord to monitor critical processes in containers. The event listener will take
following steps if it was notified one of critical processes exited unexpectedly:
The event listener will first check whether the auto-restart mechanism was enabled for this container or not. If auto-restart mechanism was enabled, event listener will kill the Supervisord process, which should cause the container to exit and subsequently get restarted.
If auto-restart mechanism was not enabled for this contianer, the event listener will enter a loop which will first sleep 1 minute and then check whether the process is running. If yes, the event listener exits. If no, an alerting message will be written into syslog.
- How to verify it
First, we need checked whether the auto-restart mechanism of a container was enabled or not by running the command show feature status. If enabled, one critical process should be selected and killed manually, then we need check whether the container will be restarted or not.
Second, we can disable the auto-restart mechanism if it was enabled at step 1 by running the commnad sudo config feature autorestart <container_name> disabled. Then one critical process should be selected and killed. After that, we will see the alerting message which will appear in the syslog every 1 minute.

Fix#5026
There is a race condition between zebra server accepts connections and bgpd tries to connect. Bgpd has a chance to try to connect before zebra is ready. In this scenario, bgpd will try again after 10 seconds and operate as normal within these 10 seconds. As a consequence, whatever bgpd tries to sent to zebra will be missing in the 10 seconds. To avoid such a scenario, bgpd should start after zebra is ready to accept connections.

Earlier today we found a bug in the SONiC TSA implementation.
TSC shows incorrect output (see below) in case we have a route-map which contains TSA route-map as a prefix.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Not consistent
```
The reason is that TSC implementation has too loose regexps in TSA utilities, which match wrong route-map entries:
For example, current TSC matches following
```
route-map TO_BGP_PEER_V4 permit 200
route-map TO_BGP_PEER_V6 permit 200
```
But it should match only
```
route-map TO_BGP_PEER_V4 permit 20
route-map TO_BGP_PEER_V4 deny 30
route-map TO_BGP_PEER_V6 permit 20
route-map TO_BGP_PEER_V6 deny 30
```
**- How I did it**
I fixed it by using egrep with `^` and `$` regexp markers which match begin and end of the line.
**- How to verify it**
1. Add follwing entry to FRR config:
```
str-s6100-acs-1#
str-s6100-acs-1# conf t
str-s6100-acs-1(config)# route-map TO_BGP_PEER_V4 permit 200
str-s6100-acs-1(config-route-map)# end
```
2. Use the TSC command and check output. It should show normal.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Normal```

I'm updating the jinja2 template to support getting SNMP information from the redis configdb.
I'm using the format approved here:
https://github.com/Azure/SONiC/pull/718
This will pave the way for us to decrement using the snmp.yml in the future.
Right now we will still be using both the snmp.yml and configdb to get variable information in order to create the snmpd.conf via the sonic-cfggen tool.
**- How I did it**
I first updated the SNMP Schema in PR #718 to get that approved as a standardized format.
Then I verified I could add snmp configs to the configdb using this standard schema. Once the configs were added to the configdb then I updated the snmpd.conf.j2 file to support the updates via the configdb while still using the variables in the snmp.yml file in parallel. This way we will have backward compatibility until we can fully migrate to the configdb only.
By updating the snmpd.conf.j2 template and running the sonic-cfggen tool the snmpd.conf gets generated with using the values in both the configdb and snmp.yml file.

This PR is in preparation to move from snmp.yml to configdb. This will more closely align with other commands in sonic and use configdb as the source of truth for snmp configuration.
Note: This is the first of 2 PR's to enable this. This PR will not change any functionality but will allow the snmp.yml file info to be put into the configdb.
Created a script that takes the snmp.yml variables and converts them to the configdb format.
Added file to dockerfile.j2 so that file is copied in the container.
Updated start.sh file to automatically run the python conversion script each time the docker container is restarted.

As part of migrating SONiC codebase from Python 2 to Python 3
**- How I did it**
- No longer install Python 2 in docker-base-buster or docker-config-engine-buster.
- Install Python 2 and pip2 in the following containers until we can completely eliminate it there:
- docker-platform-monitor
- docker-sonic-mgmt-framework
- docker-sonic-vs
- Pin pip2 version <21 where it is still temporarily needed, as pip version 21 will drop support for Python 2
- Also preform some other cleanup, ensuring that pip3, setuptools and wheel packages are installed in docker-base-buster, and then removing any attempts to re-install them in derived containers
* First cut image update for kubernetes support.
With this,
1) dockers dhcp_relay, lldp, pmon, radv, snmp, telemetry are enabled
for kube management
init_cfg.json configure set_owner as kube for these
2) Each docker's start.sh updated to call container_startup.py to register going up
As part of this call, it registers the current owner as local/kube and its version
The images are built with its version ingrained into image during build
3) Update all docker's bash script to call 'container start/stop/wait' instead of 'docker start/stop/wait'.
For all locally managed containers, it calls docker commands, hence no change for locally managed.
4) Introduced a new ctrmgrd service, that helps with transition between owners as kube & local and carry over any labels update from STATE-DB to API server
5) hostcfgd updated to handle owner change
6) Reboot scripts are updatd to tag kube running images as local, so upon reboot they run the same image.
7) Added kube_commands.py to handle all updates with Kubernetes API serrver -- dedicated for k8s interaction only.

To support dynamic buffer calculation.
This PR also depends on the following PRs for sub modules
- [sonic-swss: [buffermgr/bufferorch] Support dynamic buffer calculation #1338](https://github.com/Azure/sonic-swss/pull/1338)
- [sonic-swss-common: Dynamic buffer calculation #361](https://github.com/Azure/sonic-swss-common/pull/361)
- [sonic-utilities: Support dynamic buffer calculation #973](https://github.com/Azure/sonic-utilities/pull/973)
**- How I did it**
1. Introduce field `buffer_model` in `DEVICE_METADATA|localhost` to represent which buffer model is running in the system currently:
- `dynamic` for the dynamic buffer calculation model
- `traditional` for the traditional model in which the `pg_profile_lookup.ini` is used
2. Add the tables required for the feature:
- ASIC_TABLE in platform/\<vendor\>/asic_table.j2
- PERIPHERAL_TABLE in platform/\<vendor\>/peripheral_table.j2
- PORT_PERIPHERAL_TABLE on a per-platform basis in device/\<vendor\>/\<platform\>/port_peripheral_config.j2 for each platform with gearbox installed.
- DEFAULT_LOSSLESS_BUFFER_PARAMETER and LOSSLESS_TRAFFIC_PATTERN in files/build_templates/buffers_config.j2
- Add lossless PGs (3-4) for each port in files/build_templates/buffers_config.j2
3. Copy the newly introduced j2 files into the image and rendering them when the system starts
4. Update the CLI options for buffermgrd so that it can start with dynamic mode
5. Fetches the ASIC vendor name in orchagent:
- fetch the vendor name when creates the docker and pass it as a docker environment variable
- `buffermgrd` can use this passed-in variable
6. Clear buffer related tables from STATE_DB when swss docker starts
7. Update the src/sonic-config-engine/tests/sample_output/buffers-dell6100.json according to the buffer_config.j2
8. Remove buffer pool sizes for ingress pools and egress_lossy_pool
Update the buffer settings for dynamic buffer calculation
