Santhosh Kumar Shanmugham updated AURORA-1908:
----------------------------------------------
Description: When matching a {{ResourceRequest}} against a
{{UnusedResource}} in {{PremeptionVictimFilter.filterPremeptionVictions}} there
are 4 kinds of {{Veto}}es that can be returned. 3 out of the 4 {{Veto}}es apply
to the entire host (namely {{DEDICATED_CONSTRAINT_MISMATCH}}, {{MAINTENANCE}},
{{LIMIT_NOT_SATISFIED}} or {{CONSTRAINT_MISMATCH}}). In this case we can
short-circuit and return early and move on to the next host to consider. (was:
