Merge pull request #12 from aronr/cspace-4983

CSPACE-4983: Commented out 25 entries for fields declared as authRefs in services tenant bindings configuration, as these fields' data are associated with yet-to-be-implemented authority services (e.g. Concept, albeit coming soon; Subject; Collecting Event, et al.).  This may help temporarily simplify the complex joins being performed for refObjs searches, which in turn are causing PostgreSQL to create extremely large temp files, potentially a cause of broken refObjs queries recently on nightly.
