Summary
-------

Check is added in HBA.createTable(final HTableDescriptor desc, byte [][] splitKeys) to wait for the number of regions online equal to initial region count.
This makes HBA.createTable() synchronous.


This addresses bug HBASE-3904.

> This function as per the java doc is supposed to return true iff "all the regions in the table are available". But if the table is still being created this function may return inconsistent results (For example, when a table with a large number of split keys is created).
