Comment 12 for bug 1398817

This bug should be tracked as a blueprint due to the changes to deployment task and some implications. For example, nova host-aggregates could be used to achieve desired behavior, but that would imply only admin user context for related pre-/post-deployment tasks, see http://docs.openstack.org/havana/config-reference/content/host-aggregates.html

Also, enable_new_services could be used, but that would anyway imply additional deployment task, end-user, developer and docs impacts and cannot be tracked as a bug.

Note, that due to the deployment changes and granular deploy requirements, this improvemet cannot be backported for 6.0.
