This patch refactors all creation of RabbitMQ resources such
as users and ACLs to a define called openstack_integration::mq_user.
This will make sure RabbitMQ is automatically installed as well,
as there are times where dependencies to RabbitMQ are added to things
like Keystone which break Beaker tests in other repos (but we don't
know they're broken until the change merges).
In addition, instead of setting up dependencies on the tagged services,
we use the anchors provided which should hopefully test against them
as well.
