Partial-Bug: #1605827 - Stop spinning neutron-server service

The Openstack role doesn't need neutron-server package. It needs only neutron-common package to do neutron db sync
If we install neutron common package instead of neutron server, the neutron-server service doesn't run during openstack role provision
This speeds up Provision by preventing the respawns of that service
