> This has started as forward porting of HBASE-5494 and HBASE-5991 from the 89-fb branch
to trunk, but diverged enough to have it's own issue. 
> The idea is to implement a zk based read/write lock per table. Master initiated operations
should get the write lock, and region operations (region split, moving, balance?, etc) acquire
a shared read lock.
