Description

RS might get stuck because of  HBASE-14317. I met same problem in my hbase, and HBASE-14317 can solve this problmen very well.

But I don't get stuck when I run TestWalLockup.testLockupWhenSyncInMiddleOfZigZagSetup.
We'll never see stuck in this test case, because FailedSyncBeforeLogCloseException will break zigzagLatch.waitSafePoint(SyncFuture). Finally, zigzagLatch.releaseSafePoint() will be call, and attainSafePoint(long) get out stuck.

 Here, we add a new test case to simulate stuck RS correctly.
