Comment 1 for bug 1783347

Fixed is as part of the commit - https://github.com/Juniper/contrail-multi-cloud/pull/167.

The issue was that in Azure there are only a few regions that have availability zones. (https://docs.microsoft.com/en-us/azure/availability-zones/az-overview). The ones we tested had them. Azure claims that AZ creation on any region is a beta feature. Instead of creating the AZ OR defaulting to some AZ for a region, we will only depend on the user input.
