> As we can see lots of TODOs for region replica feature in the AssignmentManager' code.
And also, now we rely on the openSeqNum to determine whether a region has been successfully
reopened, but the openSeqNum for a non-default replica region seems unstable...
> It is too late for the 2.1.0 release so let's just add a note in ref guide to say that
region replica does not work well with AMv2 first, and then start to make it stable in follow
on minor or major release lines.
