stack updated HBASE-20708:
--------------------------
Release Note:
Introduce an InitMetaProcedure to initialize meta table for a new HBase deploy.
Marked RecoverMetaProcedure deprecated and remove the usage of it in the
current code base. We still need to keep it in place for compatibility. The
code in RecoverMetaProcedure has been moved to ServerCrashProcedure, and SCP
will always be enabled and we will rely on it to bring meta region online.
For more on the issue addressed by this commit, see the design doc for overview
and plan:

> In HBASE-20700, we make RecoverMetaProcedure use a special lock which is only
> used by RMP to avoid dead lock with MoveRegionProcedure. But we will always
> schedule a RMP when master starting up, so we still need to make sure that
> there is no race between this RMP and other RMPs and SCPs scheduled before
> the master restarts.
