Automatic merge from submit-queue.

Create prometheus configmaps before statefulset

Originally statefulset was created before configmaps and the pod would have a "FailedMount" warning for a few seconds until the configmaps are created.
Now the configmaps are created before the statefulset to avoid that warning.
