> In hbase shell, when trying to set DEFERRED_LOG_FLUSH during create or alter, 
> an undefined method `setAsyncLogFlush' exception was thrown.  
> This is due to that DEFERRED_LOG_FLUSH was deprecated and the 
> setAsyncLogFlush method was removed.  It was replaced by DURABILITY.
> DEFERRED_LOG_FLUSH=>true is the same as DURABILITY=>'ASYNC_WAL'
> The default is DURABILITY=>'SYNC_WAL', which is the same as the default 
> DEFERRED_LOG_FLUSH=>false
> We should ask user to use the DURABILITY setting.  In the meantime, for 
> backward compatibility, the hbase shell should still allow setting 
> DEFERRED_LOG_FLUSH.  Internally, instead of calling setAsyncLogFlush, it 
> should call setDurability
