----------------------------------

[~mbertozzi]
Thanks for the quick review.
For the location of the new files, what about I move them to hbase.procedure.flush?
There are indeed a lot of duplicate code in the ProcedureManager side and in the SubProcedure
side.
Unfortunately some of them are common boilerplate code to set up procedure and get it going.
Good point. I agree we should be able to provide something like a base template class to include
the common. In another JIRA?

> Currently, user can trigger table flush through hbase shell or HBaseAdmin API.  To flush
the table cache, each region server hosting the regions is contacted and flushed sequentially,
which is less efficient.
> In HBase snapshot global procedure is used to coordinate and flush the regions in a distributed
way.
> Let's provide a distributed table flush for general use.
