Create a podman role

This change creates a role using the podman content from
THT[0]. This role will run through all of the tasks found
within the THT file, and implements molecule tests coving
the functionality.

Test Matrix:
  - default - Runs through the role top to bottom
  - install - Runs only the install portions of the role
  - login - Runs only the login portion of the role
