In Nova cells v1 has been deprecated since Ocata but we have no notices about it. This adds warnings about it being deprecated and will be removed. The functionality in nova::cells when passing create_cells parameter is broken and has therefore been removed and instead outputs a warning and is deprecated. A known issue has been added to the release notes to inform about this. It's probably safe to say that nobody is using it since it has been broken since we switched over to transport_url for rabbit, it's also safe to probably assume that no deployments that run cell v1 right now will be running a later version of Nova.
