Allow specifying individual host during nova instance provisioning
Acc to Pushkar, specifying az parameter to hostname (some variation) allows creating VM directly on a specific host. Otherwise, one has to create a host-aggregate with specific tags, then create flavor with the same tags. This is unnecessary if we can get that option in UI and UI can send data to nova API.
This is a terrible concept. This has absolutely no consideration for the self-service user. Unaware of the physical host, this user.

This should automatically happen if you provision an instance from the screen showing the list of instances present on that particular hypervisor., at "Infrastructure > (host) -> Instances". There isn't an instance provision button there presently. Probably that is the only place in the UI where this behavior should occur.
This is a bad idea... This doesn't think about the Self Service User at all. This user is un-aware of the physical host.
