Re-land "Copy over failed update/tests into their own tree hierarchy."

The old version of the parallel library would hang because of too much data as part of the object being passed around. Since then, David James has refactored the au_test_harness to use the chromite parallel library which does not have this hanging issue. Re-landing.
