Release Apache Kudu 1.10.0
[tablet] reinforce the CountLiveRows API

In the recent patch 13426, I found that the CountLiveRows API is
not safe after the tablet is been shut down. Though the API has
not been used by any real users except test cases, I think it's
necessary to add this patch to the 1.10.x release in progress if
it's possible.
