------------------------------------------------------------
Here is the WIP patch introducing new state 'shadow' to region so that
AM/balancer can skip the assignment and at the same time the writes and reads
can be served by the region.
To make the region a shadow region using transaction approach.
[~jeffreyz] is this approach fine for you?
If it's ok, I will add more tests,APIs and utils tomorrow and upload new patch.
Ping [~jxiang] [~stack]
Thanks.
