Precaching spec error due to invalid policy combination reported as precaching/backup failures on spokes

When precaching is enabled with catalog source policy only (i.e. subscription policy missing in the cgu policy list), precaching can not proceed without actual operator info. The CGU conditions reported are misleading.

1. Create a cgu with precaching enabled and catalog source policy only
2.
3.

CGU should not proceed as if actual precaching job failed on all clusters. It should remain in not started state so that admin could fix the policies. Also the reason message should not be "InvalidPlatformImage".
