> When working on HBASE-20666, I found out HBASE-18350 did not get ported to branch-1,
which causes procedure to hang when #moveTables called sometimes. 
> After looking into the 18350 patch, seems it's important since it fixes 4 issues. This
Jira is an attempt to backport it to branch-1.
> Edited: Aug26.
> After reviewed the HBASE-18350 patch. I decided to only port part 2 of the patch.
> Because part1 and part3 is AMv2 related. I won't touch is since Amv2 is only for branch-2

> Subject: [PATCH] HBASE-18350 RSGroups are broken under AMv2
> - Table moving to RSG was buggy, because it left the table unassigned.
>   Now it is fixed we immediately assign to an appropriate RS
>   (MoveRegionProcedure).
> *- Table was locked while moving, but unassign operation hung, because*
>   *locked table queues are not scheduled while locked. Fixed.   ---- port this one.*
> - ProcedureSyncWait was buggy, because it searched the procId in
>   executor, but executor does not store the return values of internal
>   operations (they are stored, but immediately removed by the cleaner).
> - list_rsgroups in the shell show also the assigned tables and servers.
