title: Clone azure app service from one subscription to another under the same tenant
body: <p>We are trying to clone or restore AppServices from a stable environment in Azure while provisioning new environments.
  The stable environment is in one Subscription but the new environments to be created are in another subscription. Both subscriptions are in the same tenant.
  Ideally I would like to clone the AppServices from the stable envs when provisioning new environments instead of back/restore.
  Is there any way through ARM templates or Powershell to clone an AppService under one subscription to
  another subscription under the same Tenant?</p>
