LTPA Manager does not deep copy the short-hand applicationImage syntax from wlapp to the LTPA Job

[kabicin]

The WebSphereLibertyApplication .spec.applicationImage supports a short-hand syntax i.e. applicationImage: my-app that allows the operator to search for an OpenShift ImageStream named my-app to retrieve the image reference.

When enabling the .spec.manageLTPA: true the operator simply passes the .spec.applicationImage value from the WebSphereLibertyApplication to the LTPA Job. Instead, it should do a deep parsing of image reference from the ImageStreamTag object before passing the applicationImage for the Job to use.

Current workaround for 1.3.0 is to copy the .status.imageReference image into the .spec.applicationImage field for all WebSphereLibertyApplications setting .spec.manageLTPA to true.
