OKD-380: Add missing namespace to image trigger annotations

The image.openshift.io/triggers annotation on database Deployments is
missing the namespace field in the ImageStreamTag reference. Without it,
the image trigger controller looks for ImageStreams in the user's namespace
instead of 'openshift', causing image resolution to fail.

Add "namespace":"${NAMESPACE}" to the trigger from object in both
postgresql-persistent and postgresql-ephemeral templates.
