Fixed hosts inclusion when requiring the lxc_hosts role

The lxc host role was being pinned to specific hosts under the assumption
that only those host types would ever run lxc containers. This becomes an
issue when the host groups have been used outside of our "nornal" pattern
used in the gate. Simple changes to the "openstack_user_config.yml" file
can cause containers to be built in hosts not covered by our current pins.

Common example where the old group would not work:
  http://paste.openstack.org/show/565045/

To correct this issue a new play has been added under "common-plays" which
generates a group of known hosts which we know will require the "lxc_host"
role.
