Description

Currently we need to create table and then move it to desired RSGroup which cost HM assignment twice, considering table with many regions it will be huge.

We have a use case where user want to create table with rsgroup. HBASE-22695 already implemented this feature in master branch but not ported to branch-2 because master and branch-2 implementations are different. This JIRA aims to implement this feature in branch-2.

But unlike master branch, rsgroup information from TableDescriptor is used only while creating the table to keep the changes minimum.
