Mikhail Antonov updated HBASE-15137:
------------------------------------
    Attachment: HBASE-15137.v3.patch

Added handling for CQTBE and relevant checks for RetriesWithDetailsExceptions, 
which is tricky to unwrap, added a test.

Added a flag to PFFE class indication whether or not operations is guaranteed 
to not be attempted by server (for example, CQTBE does guarantee that, but 
CallTimeoutException does not)

> CallTimeoutException and CallQueueTooBigException should trigger PFFE

> If a region server is backed up enough that lots of calls are timing out then 
> we should think about treating a server as failing.
