Glance DCN: Remove unnecessary configuration and default to az0

- Remove the `customServiceConfig` from the Glance template
  since it's different for each Glance API pod.

- Remove undefined backends from `enabled_backends` in az1 and az2

- Call the glance backend at AZ0 `az0` instead of `default`.
