The issue was reported to scapy devs secdev/scapy#3369, the fix is secdev/scapy#3371, however there is no released scapy version with this fix right now, thus decided to build scapy v2.4.5 from sources and apply the fix in a form of a patch.

Reduce the disk space taken up during bootup and runtime.
1. Remove python package cache from the base image and from the containers.
2. During bootup, if logs are to be stored in memory, then don't create the `var-log.ext4` file just to delete it later during bootup.
3. For the partition containing `/host`, don't reserve any blocks for just the root user. This just makes sure all disk space is available for all users, if needed during upgrades (for example).
* Remove pip2 and pip3 caches from some containers
Only containers which appeared to have a significant pip cache size are
included here.

- Create a script in the orchagent docker container which listens for these encapsulated packets which are trapped to CPU (indicating that they cannot be routed/no neighbor info exists for the inner packet). When such a packet is received, the script will issue a ping command to the packet's inner destination IP to start the neighbor learning process.
- This script is also resilient to portchannel status changes (i.e. interface going up or down). An interface going down does not affect traffic sniffing on interfaces which are still up. When an interface comes back up, we restart the sniffer to start capturing traffic on that interface again.
**- Why I did it**
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
Install the necessary python3 dependent packages to convert restore_neighbor.py
to support python3 as python2 is EOL. See: Azure/sonic-swss#1542

**- Why I did it**
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
As part of the transition from Python 2 to Python 3, we are installing both pip2 and pip3 in the slave and config-engine containers. This PR replaces calls to `pip` in these containers with an explicit call to `pip2` to ensure the proper version of pip is executed, no matter which version of pip is aliased to `pip`, as we no longer rely on that alias.
Also some other pip-related cleanup
* Install ndppd during image build, and copy config files to image
* Configure proxy settings based on config DB at container start
* Pipe ndppd output to logger inside container to log output in syslog
This PR limited the number of calls to sonic-cfggen to one call
per iteration instead of current 3 calls per iteration.
The PR also installs jq on host for future scripts if needed.

Added a service: "restore_neighbors" to restore neighbor table into
kernel during system warm reboot. The service is started by supervisord
in swss docker when the docker is started.
In case system warm reboot is enabled, it will try to restore the neighbor
table from appDB into kernel through netlink API calls and update the neighbor
table by sending arp/ns requests to all neighbor entries, then it sets the
stateDB flag for neighsyncd to continue the reconciliation process.

* Fix potential blackholing/looping traffic and refresh ipv6 neighbor to avoid CPU hit
In case ipv6 global addresses were configured on L3 interfaces and used for peering,
and routing protocol was using link-local addresses on the same interfaces as prefered nexthops,
the link-local addresses could be aged out after a while due to no activities towards the link-local
addresses themselves. And when we receive new routes with the link-local nexthops, SONiC won't insert
them to the HW, and thus cause looping or blackholing traffic.
Global ipv6 addresses on L3 interfaces between switches are refreshed by BGP keeplive and other messages.
On server facing side, traffic may hit fowarding plane only, and no refresh for the ipv6 neighbor entries regularly.
This could age-out the linux kernel ipv6 neighbor entries, and HW neighbor table entries could be removed,
and thus traffic going to those neighbors would hit CPU, and cause traffic drop and temperary CPU high load.
Also, if link-local addresses were not learned, we may not get them at all later.
It is intended to fix all above issues.
Changes:
Add ndisc6 package in swss docker and use it for ipv6 ndp ping to update the neighbors' state on Vlan interfaces
Change the default ipv6 neighbor reachable timer to 30mins
Add periodical ipv6 multicast ping to ff02::11 to get/refresh link-local neighbor info.
* Fix review comments:
Add PORTCHANNEL_INTERFACE interface for ipv6 multicast ping
format issue
* Combine regular L3 interface and portchannel interface for looping
* Add ndisc6 package to vs docker
Set the ECMP/LAG hash seed to 10 when the switch is a ToR, 20 when the switch
is a Leaf, 0 otherwise.

- Add Everflow DST IP to minigraph file

The reason is that /etc/network/interfaces file is in base image. After booting,
docker-swss is not ready and thus the empty VLAN interfaces cannot be created
when the brctl is pointing to the binary inside the swss docker.
Add the bridge-utils into the base image and add bridge_ports none to the
/etc/network/interfaces file so that after boot-up the empty VLAN interfaces
will be created to let the members to join later.
