[tripleo] Switch to tripleo-container-manage by default (replacing Paunch)

Hi folks,

Some work has been done to replace Paunch and use the new
"podman_container" Ansible module; It's possible thanks to a role that is
now documented here:
https://docs.openstack.org/tripleo-ansible/latest/roles/role-tripleo-container-manage.html

While some efforts are still ongoing to replace container-puppet.py (which
uses Paunch to execute a podman run); the tripleo-container-manage role has
reached stability and enough maturity to be the default now.
I would like to give it a try and for that I have 2 patches that would need
to be landed:
https://review.opendev.org/#/c/700737
https://review.opendev.org/#/c/700738

The most popular question that has been asked about $topic so far is: how
can I run paunch debug to print the podman commands.
Answer:
https://docs.openstack.org/tripleo-ansible/latest/roles/role-tripleo-container-manage.html#check-mode

Please raise any concern here and we'll address it.
Hopefully we can make the default on time before U cycle ends.

On a side note: I prepared all the backports to stable/train so the feature
will be available in that branch as well.

Thanks,
