Bug Description

Currently OS API doesn't accept availability zone parameter so there is no way to instruct scheduler (simpleScheduler) to launch VM instance on specific host of specified zone.

Hmm, the external caller should have no indication of the hosts within a nova deployment.

Only admin users would be allowed to launch server on specific host of specific zone. In Openstack EC2 API you can do this by specifying --placement group parameter with the syntax <zone>:<host> and is recognized only if you are using simpleScheduler. I want to do the same in OS API. Also I will modify nova-manage ServiceCommands class to expose additional zone information along with the service.
