Add new stack phase: post-extra

The current existing phases "post-config" and "extra" are not
sufficient to allow local.conf overrides to extra type services
because they run after the services are installed and configured.
This commit introduces a new phase called "post-extra" that runs
after these existing phases. With this change, users are able to
leverage local.conf to provide overridden options to services
like Tempest.
