> 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.
