Remove libvirt packaged dependencies

Nova services are now running in the containers but we have still
a lot of libvirt packages installed on Overcloud systems.
To delete unnecessary packages on host systems I'm removing following
dependencies:
* modifying NovaLibvirtGuests service to run in containers and generate
  config files for libvirt-guests
* removeing hard dependencies for libvirt-guests service to
  virt-guest-shutdown.target.
  packages.
