Use tox-lsr 2.14.1; use py39 for ansible related checks; use podman instead of docker

[richm]

CI is broken pretty hard right now due to tox 4.x and ansible-test images. It will take non-trivial effort to make tox-lsr work with tox 4.x. So, in the meantime:

• tox-lsr 2.14.1 forces the use of tox 3.x
• tox-lsr 2.14.0 moved to use ansible-core 2.14 which does not support python 3.8 - rather than try to revert that, I moved some of the ansible related checks to use python 3.9
• for some reason the latest ansible-test image does not work with docker - so install the podman-docker package to "fool" the system into using podman instead of docker - the package is only available on ubuntu-latest - in order to do this, we first have to remove moby-cli (aka docker-client)

This isn't pretty, and I have a big plan to replace all of this stuff with

• individual github actions for yamllint, ansible-lint, ansible-test, etc.
• removal of py, pylint, etc. tests for non-python roles

We need CI to be working right now, so please bear with me as we try to get this working again, and fix it the "right way" soon.
