Unsuccessful table creation leaves entry in hbase:rsgroup table

If a table creation fails in a cluster enabled with rsgroup feature, the table is still listed as part of default rsgroup.

To recreate the scenario:

• Create a namespace (NS) with number of region limit
• Create table in the NS which satisfies the region limit by pre-splitting
• Create a new table in the NS which will fail
• list_rsgroup will show the table being part of default rsgroup and data can be found in hbase:rsgroup table

Would be good to revert the entry when the table creation fails or a script to clean up the metadata.
