Support waiting until deployment is completed

Hi!

I am looking for a feature to be able to make this action wait until the deployment is actually completed. Now the action seems to be considered "completed" when the signal is sent away to Azure to initiate the deployment. I would like the action to wait until the new revision is deployed and is up and running **OR** until the deployment actually failed. It would be great to have this feature so that we don't have to implement it ourselves.

BR,
Rasmus
