Title:
  It is not possible to select AZ for new Cinder volume during the VM
  creation

Status in OpenStack Dashboard (Horizon):
  New
Status in OpenStack Compute (nova):
  New

Bug description:
  Steps To Reproduce:
  1. Deploy OpenStack cluster with several Nova availability zones, for example, 'nova1' and 'nova2' and with several Cinder availability zones, for example, 'storage1' and 'storage2' (availability zones for Nova and Cinder should be different).
  2. Login to Horizon dashboard and navigate to Project > Instances
  3. Click on 'Launch Instance' button
  4. Set all required parameters, select Nova AZ 'nova1' for new VM and select Instance Boot Source = "Boot from image (creates new volume)"
  5. Click on 'Launch' button

  Observed Result:
  Instance will fail with "Failure prepping block device" error (please see attached screenshot horizon_az_bug.png)

  Expected Result:
  As a user I expect that Horizon UI will provide me the ability to select the availability zone for new volume if I want to create new volume and boot VM from it. We can't use Nova AZ as availability zone for Cinder volume because these zones are different availability zones (we can have, for example, 1 Nova availability zones and many Cinder availability zone or one Cinder AZ and many Nova AZs - it depends on users needs).
