PIG-3618 Replace broadcast edges with scatter/gather edges in union
Review Request #16165 - Created Dec. 11, 2013 and submitted
Replace broadcast edges with scatter/gather edges for union. I also changed the name of POPackage from POBroadcastTezLoad to POUnionTezLoad.
Ran tez unit tests and e2e tests. I set the parallel of union in the e2e test case to 2.

Let's put a comment subject to change after TEZ-661. waitingQueue seems unnecessary since we can remember where we are in POUnionTezLoad, and this could increase the chance of OOM. But we don't need to address it now, since it is just a temporary fix.
