Split x/monasca-vagrant out to its own Gerrit ACL

The x/monasca-vagrant project started out sharing the Gerrit
configuration for other projects maintained by the OpenStack Monasca
team within the openstack/ namespace. Give this repository a
separate config in its own namespace in order to not have it inherit
from openstack/meta-config.
