To optimize stop on warm boot, added kill for containers
Use service "kill" in the shutdown path for fast and warm reboot. For all other reload methods, service "stop" is used.
This is done to save time in shutdown path, and to overall improve the time spent in warm and fast reload.
How - Use service_mgmt.sh to trigger common logic to initiate kill (fast/warm) or stop (cold) for database.sh, radv.sh, snmp.sh, telemetry.sh, mgmt-framework.sh

The haveged service file in Debian Buster specifies that haveged should
start after systemd-random-seed starts (this was removed in Bullseye
after systemd changes caused a bootloop). This is a bit
counterproductive, since haveged is meant to be used in environments
with minimal sources of entropy, but one of the checks that
systemd-random-seed does is to verify that entropy is present.
Therefore, override the default .service file for haveged that moves
systemd-random-seed to the Before list, allowing it to start before
systemd-random-seed checks the system entropy level. (systemd doesn't
allow removing items from dependency/ordering entries such as After= and
Before=, so the entire .service file has to be overwritten.)
Note that despite this, haveged takes up to two seconds to actually
start working, so systemd-random-seed may still block for about two
seconds. However, this still allows other work (such as running
rc.local) to proceed a bit sooner.

As a part of warmboot, redis database is dumped:
c97fe546e5/scripts/fast-reboot (L269)
However, this dump file is deleted, after it is loaded back into db post reboot.
The DB dump can be useful for debugging purpose, hence taking a backup of it can be useful.
Instead of deleting the dump, rename and keep the dump.
#### Why I did it
Use a predefined variable to get vendor information when the swss docker container is created
#### How I did it
Use `{{ sonic_asic_platform }}` instead of `$SONIC_CFGGEN -y /etc/sonic/sonic_version.yml -v asic_type`
#### How to verify it
Manually test.
#### Why I did it
Create a target for delayed service timers. Few services in sonic have delayed to speed up the bring up of the system and essential services. However there is no way to track when they start. This will be a problem when executing config reload as config reload expects all services to be up. Hence grouped all the timers that trigger the delayed services under one target so that they could be tracked in 'config reload' command
#### How I did it
Created delay.target service and add created dependency on the delayed targets.

This PR creates a directory firmware on the HOST with the path /usr/share/sonic/firmware, as well as this is
mounted on PMON container with the same path /usr/share/sonic/firmware. This is required for firmware
upgrade support for muxcable as currently by design all Y-Cable API's are called by xcvrd. As such if CLI has
to transfer a file to PMON we need to mount a directory from host to PMON just for getting the firmware files.

Why I did it
The SONiC switches get their docker images from local repo, populated during install with container images pre-built into SONiC FW. With the introduction of kubernetes, new docker images available in remote repo could be deployed. This requires dockerd to be able to pull images from remote repo.
Depending on the Switch network domain & config, it may or may not be able to reach the remote repo. In the case where remote repo is unreachable, we could potentially make Kubernetes server to also act as http-proxy.
How I did it
When admin explicitly enables, the kubernetes-server could be configured as docker-proxy. But any update to docker-proxy has to be via service-conf file environment variable, implying a "service restart docker" is required. But restart of dockerd is vey expensive, as it would restarts all dockers, including database docker.
To avoid dockerd restart, pre-configure an http_proxy using an unused IP. When k8s server is enabled to act as http-proxy, an IP table entry would be created to direct all traffic to the configured-unused-proxy-ip to the kubernetes-master IP. This way any update to Kubernetes master config would be just manipulating IPTables, which will be transparent to all modules, until dockerd needs to download from remote repo.
How to verify it
Configure a switch such that image repo is unreachable
Pre-configure dockerd with http_proxy.conf using an unused IP (e.g. 172.16.1.1)
Update ctrmgrd.service to invoke ctrmgrd.py with "-p" option.
Configure a k8s server, and deploy an image for feature with set_owner="kube"
Check if switch could successfully download the image or not.

Why I did it
Currently we leveraged the Supervisor to monitor the running status of critical processes in each container and it is more reliable and flexible than doing the monitoring by Monit. So we removed the functionality of monitoring the critical processes by Monit.
How I did it
I removed the script process_checker and corresponding Monit configuration entries of critical processes.
How to verify it
I verified this on the device str-7260cx3-acs-1.
Why I did it
In upgrade scenarios, where config_db.json is not carry forwarded to new image, it could be left w/o TACACS credentials.
Added a service to trigger 5 minutes after boot and restore TACACS, if /etc/sonic/old_config/tacacs.json is present.
How I did it
By adding a service, that would fire 5 mins after boot.
This service apply tacacs if available.
How to verify it
Upgrade and watch status of tacacs.timer & tacacs.service
You may create /etc/sonic/old_config/tacacs.json, with updated credentials
(before 5mins after boot) and see that appears in config & persisted too.

How I did it
I borrowed the system tool Monit to run a script memory_checker which will periodically check the memory usage of streaming telemetry container. If the memory usage of telemetry container is larger than the pre-defined threshold for 10 times during 20 cycles, then an alerting message will be written into syslog and at the same time Monit will run the script restart_service to restart the streaming telemetry container.

The azure-storage package depends on the cryptography package. Newer
versions of cryptography require the rust compiler, the correct version
for which is not readily available in buster. Hence we pre-install an

[multi_asic][vs]: Add dependency in teamd service to start after topology service.
- Why I did it
In multi-asic VS, topology service is run after database service to set up the internal asic topology.
swss and syncd have a dependency to start after topology service is run so that the interfaces are moved to right namespace and created in the right namespace. In case of multi-asic vs, during the initial boot up, when there is no configuration added, teamd service starts and swss/syncd do not start as topology service does not start. Upon loading configuration using config_db or minigraph, swss and sycnd start up , but teamd is not restarted as swss is not stopped and started. This causes teamd to be in a bad state and requires a reload of config.
- How I did it
Add dependency in teamd service to start after topology service is completed.
- How to verify it
No change in single asic vs or platform.
No change in multi-asic regular image.
Change only in multi-asic VS. Bring up a multi-asic VS image without any configration, teamd service will fail to start due to dependency failure. Load minigraph, start topology service, load configuration, ensure all services come up.

**- Why I did it**
This PR aims to monitor the running status of each container. Currently the auto-restart feature was enabled. If a critical process exited unexpected, the container will be restarted. If the container was restarted 3 times during 20 minutes, then it will not run anymore unless we cleared the flag using the command `sudo systemctl reset-failed <container_name>` manually.
**- How I did it**
We will employ Monit to monitor a script. This script will generate the expected running container list and compare it with the current running containers. If there are containers which were expected to run but were not running, then an alerting message will be written into syslog.
**- How to verify it**
I tested this feature on a lab device `str-a7050-acs-3` which has single ASIC and `str2-n3164-acs-3` which has a Multi-ASIC. First I manually stopped a container by running the command `sudo systemctl stop <container_name>`, then I checked whether there was an alerting message in the syslog.
