-----------------------------------------------------------------
Nit: Remove the '@Deprecated' tags from the renamed methods. The deprecated
methods have been effectively removed and replaced with a new API.
Edit: Committer, please also insure the deprecated methods appear as such in
0.96 branch.

> By the new write thread model introduced by
> [HBASE-8755|https://issues.apache.org/jira/browse/HBASE-8755], some
> deferred-log-flush/Durability API/code/names should be change accordingly:
> 1. no timer-triggered deferred-log-flush since flush is always done by async
> threads, so configuration 'hbase.regionserver.optionallogflushinterval' is no
> longer needed
> 2. the async writer-syncer-notifier threads will always be triggered
> implicitly, this semantic is that it always holds that
> 'hbase.regionserver.optionallogflushinterval' > 0, so deferredLogSyncDisabled
> in HRegion.java which affects durability behavior should always be false
> 3. what HTableDescriptor.isDeferredLogFlush really means is the write can
> return without waiting for the sync is done, so the interface name should be
> changed to isAsyncLogFlush/setAsyncLogFlush to reflect their real meaning
