**- 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
libxslt-dev and libz-dev are dependencies for lxml==4.6.1 which is required for pyangbind==0.8.1
lxml-4.6.2-cp37-cp37m-manylinux1_x86_64.whl is directly downloaded in amd64 whereas in arm this is built from lxml-4.6.2.tar.gz

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.
The orchagent and syncd need to have the same default synchronous mode configuration. This PR adds a template file to translate the default value in CONFIG_DB (empty field) to an explicit mode so that the orchagent and syncd could have the same default mode.
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.
This change adds support to build dockers using buster as base.
- Define docker-base-buster using docker-base-stretch as starting point
- Define docker-config-engine-buster using docker-config-engine-stretch as starting point.
- sonic-mgmt-framework docker is updated to build using buster as base
