container: add always tag on gather fact tasks

If we execute the site-container.yml playbook with specific tags (like
ceph_update_config) then we need to be sure to gather the facts otherwise
we will see error like:

The task includes an option with an undefined variable. The error was:
'ansible_hostname' is undefined

This commit also adds missing 'gather_facts: false' to mons plays.
