[part of hbase-1583] We wait on leases to expire before regionserver goes down.  Rather, just
let client fail
-------------------------------------------------------------------------------------------------------------

                 Key: HBASE-1609
                 URL: https://issues.apache.org/jira/browse/HBASE-1609
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: stack
             Fix For: 0.20.0


Addressing this issue will help hbase-1583.  We should do for 0.20.0 and perhaps for 0.19.x
even.

Currently, if outstanding leases, in HRegion close, we'll hang until lease expires.  Could
be a minute.  Could be worse, the client might come in and renew the lease a few times at
least till it finishes out the region.  This gets in way of regionserver shutting down fast.
 

J-D suggests that regionserver should just go down and outstanding clients should fail rather
than try and be nice to outstanding clients (in his case, his MR job had failed so no clients...
but we insist on lease expiring).
