Add backwards compat handling for FrozenJob
Change I9425ccf9c532e59b96040d182e2ffa3b5c3321be is not compatible with a rolling restart because a second scheduler may try to write a FrozenJob after reading one without these attributes. Handle this gracefully by not writing them out if they are not present. Change-Id: I4fcae4ee81a09552c7c206afdf5b7ab700d860f5
