states: Rename openstack, add baremetal_init

To align with new cluster naming convention, rename 'openstack'
state file to 'openstack_noha'.
While at it, factor out baremetal setup from 'virtual_control_plane'
into a new state that will be reused in upcoming scenarios, remove
useless sync_all (automatically done after node reboot).
