Delete slop2

Vinoth, I wanted to register Slops for QuotaExceededException. For Delete, we send all parallel requests and if some of them currently fails with QuotaException, we just ignore it. While modifying I realized that it is a copy/paste mess.  Application thread queues the error in handleResponseError for UnreachableStoreException  and PerformDeletedHintedHandoff looks at the list and performs the action. The error are being reported multiple times ( as the error is not removed from the response map and it had multiple other bugs)

Now I am just routing them through the same method and just deciding whether to call the method from call back or application thread ( Still race conditions are there) but it is cleaner and easier to reason about.

Please let me know if you need more information.
