purge: remove docker_* task

All containers are removed when systemd stops them.
There is no need to call this module in purge container playbook.

This commit also removes all docker_image task and remove all container
images in the final cleanup play.

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1776736
