Logan V 676c868111 Target specific host groups instead of 'all'
The playbook targets 'all', which is a dynamically generated ansible
group that contains all hosts. This potentially targets hosts that
are not managed by OSA but exist in the same inventory namespace.

This now targets the OSA hosts and containers var that contains
the group names this should target.
