      Description

      [INFO] Running org.apache.hadoop.hbase.master.TestServerCrashProcedureCarryingMetaStuck
      [ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 41.604 s <<< FAILURE! - in org.apache.hadoop.hbase.master.TestServerCrashProcedureCarryingMetaStuck
      [ERROR] test(org.apache.hadoop.hbase.master.TestServerCrashProcedureCarryingMetaStuck) Time elapsed: 30.496 s <<< ERROR!

      The META_QOS is introduced by HBASE-21754 and misused in HBASE-21907 as the name is a bit ambiguous. To prevent misusing in the future, let's deprecated the META_QOS in HConstants, and introduce a META_TRANSITION_QOS somewhere that is not IA.Public.
