What problem does this PR solve?
It takes too long (20s) for a follower PD to return an error to client. It may cause a longer unavailable time when PD leader changes.
Note: The client will not wait for 20s, but will timeout after 3 seconds.
What is changed and how it works?
Check lease before alloc ts.
