#### Why I did it
Adds P4RT container to SONiC for PINS
The P4RT app is covered by this HLD:
https://github.com/pins/SONiC/blob/master/doc/pins/p4rt_app_hld.md
#### How I did it
Followed the pattern and templates used for other SONiC applications
#### How to verify it
Build SONiC with INCLUDE_P4RT set to "y".
Verify that the resulting build has a container called "p4rt" running.
You can verify that the service is up by running the following command on the SONiC switch:
```bash
sudo netstat -lpnt | grep p4rt
```
You should see the service listening on TCP port 9559.
#### Which release branch to backport (provide reason below if selected)
None

This PR is part of SONiC Application Extension
Depends on #5938
- Why I did it
To provide an infrastructure change in order to support SONiC Application Extension feature.
- How I did it
Label every installable SONiC Docker with a minimal required manifest and auto-generate packages.json file based on
installed SONiC images.
- How to verify it
Build an image, execute the following command:
admin@sonic:~$ docker inspect docker-snmp:1.0.0 | jq '.[0].Config.Labels["com.azure.sonic.manifest"]' -r | jq
Cat /var/lib/sonic-package-manager/packages.json file to verify all dockers are listed there.
- Support compile sonic arm image on arm server. If arm image compiling is executed on arm server instead of using qemu mode on x86 server, compile time can be saved significantly.
- Add kernel argument systemd.unified_cgroup_hierarchy=0 for upgrade systemd to version 247, according to #7228
- rename multiarch docker to sonic-slave-${distro}-march-${arch}

**- Why I did it**
Prior to SONiC using Debian Buster, we needed to build Python 3.5 or newer from source for installation in the SNMP container, becuase it wasn't available from the Debian repository for Jessie or Stretch. Now that all containers are based on Buster, we simply install Python 3.7 from the Debian repository in the host as well as all containers. We are no longer building Python 3 from source, so the Makefile is unused and we no longer need to install build dependencies in the slave containers.
**- How I did it**
- Remove Python 3 makefile
- No longer install Python 3 build dependencies in the slave containers.
**- 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
for exmaple, for arm64, the sonic-slave docker image name
is sonic-slave-arm64-$(USER)
for amd64, the docker image is kept as it is

The maintainers of the m2crypto Python package pushed two new versions of the package to PyPI today, version 0.37.0 followed a few hours later by 0.37.1 (https://pypi.org/project/M2Crypto/0.37.1/#history). It appears as though these packages are failing to build/install properly in our image.
The problem was noticed in the Jessie container, where we were not previously explicitly installing the Debian m2crypto package. As part of this PR, I install m2crypto via pip in the Jessie container and pin down the version. I also modified the Stretch and Buster Dockerfiles to install the package vi pip in the same fashion for consistency.
**- Why I did it**
We were building a custom version of Supervisor because I had added patches to prevent hangs and crashes if the system clock ever rolled backward. Those changes were merged into the upstream Supervisor repo as of version 3.4.0 (http://supervisord.org/changes.html#id9), therefore, we should be able to simply install the vanilla package via pip. This will also allow us to easily move to Python 3, as Python 3 support was added in version 4.0.0.
**- How I did it**
- Remove Makefiles and patches for building supervisor package from source
- Install Python 3 supervisor package version 4.2.1 in Buster base container
- Also install Python 3 version of supervisord-dependent-startup in Buster base container
- Debian package installed binary in `/usr/bin/`, but pip package installs in `/usr/local/bin/`, so rather than update all absolute paths, I changed all references to simply call `supervisord` and let the system PATH find the executable to prevent future need for changes just in case we ever need to switch back to build a Debian package, then we won't need to modify these again.
- Install Python 2 supervisor package >= 3.4.0 in Stretch and Jessie base containers
Upgrading pip3 after pip2 caused the pip command to be aliased to the pip3 command. However, since we are still transitioning from Python 2 to Python 3, most pip commands in the codebase are expecting pip to alias to pip2. The proper solution here is to explicitly call pip2 and pip3, and no longer call pip, however this will require extensive changes and testing, so to quickly fix this issue, we upgraded pip2 after pip3 to ensure that pip2 is installed after pip3.
We were building our own python-click package because we needed features/bug fixes available as of version 7.0.0, but the most recent version available from Debian was in the 6.x range.
"Click" is needed for building/testing and installing sonic-utilities. Now that we are building sonic-utilities as a wheel, with Click specified as a dependency in the setup.py file, setuptools will install a more recent version of Click in the sonic-slave-buster container when building the package, and pip will install a more recent version of Click in the host OS of SONiC when installing the sonic-utilities package. Also, we don't need to worry about installing the Python 2 or 3 version of the package, as the proper one will be installed as necessary.
CONiC config gen requires jinja2<3.0.0 for stretch and byangbind
versions 0.60.0/0.80.1 for Python 2/3 respectively. byangbind
is installed in the build docker because when it installed it
pulls enum34 as dependent package which is not required for
Python 3 and it breaks the build.

[sonic-yang-models]: First version of yang models for Port, VLan, Interface, PortChannel, loopback and ACL.
YANG models as per Guidelines.
Guideline doc: https://github.com/Azure/SONiC/blob/master/doc/mgmt/SONiC_YANG_Model_Guidelines.md
[sonic-yang-models/tests]: YANG model test code and JSON input for testing.
[sonic-yang-models/setup.py]: Build infra for yang models.
**- What I did**
Created Yang model for Sonic.
Tables: PORT, VLAN, VLAN_INTERFACE, VLAN_MEMBER, ACL_RULE, ACL_TABLE, INTERFACE.
Created build infra files using which a new package (sonic-yang-models) can be build and can be deployed on sonic switches. Yang models will be part of this new package.
**- How I did it**
Wrote yang models based on Guideline doc:
https://github.com/Azure/SONiC/blob/master/doc/mgmt/SONiC_YANG_Model_Guidelines.md
and
https://github.com/Azure/SONiC/wiki/Configuration.
Wrote python wheel Package infra which runs test for these Yang models using a json files which consists configuration as per yang models. These configs are for negative tests, which means we want to test that most must condition, pattern and when condition works as expected.
**- How to verify it**

DHCP relay MONitor (dhcpmon) keeps track of DORA messages. If DHCP Relay
is detected to be not forwarding DORA message, dhcpmon will log such event
to syslog. Under the hood dhcpmon keeps counts of clients DR messages,
forwarded DR messages, DHCP server OA messages, and forwarded OA messages.
dhcpmon will check every 12 sec (configurable) if counts are monotonically
increasing and record snapshot of those counters. dhcpmon will report
discrepancies when detected between current counters and snapshot counters.
