HBASE-29148: BufferedMutator should be able to flush after buffering a certain number of mutations

[charlesconnell]

At my company I've been experimenting with enabling hbase.rpc.rows.size.threshold.reject on our RegionServers as a protective measure, to prevent Java OOMs caused by large Multi requests. This has caused issues for some clients using BufferedMutators, which send large batches of mutations, sometimes all to a single RegionServer. It the BufferedMutator had a way to flush before hitting the RegionServer's hbase.rpc.rows.warning.threshold, then it could gets its mutations done successfully. This is easy to add.
