[close #757] Support verifying primary for check_txn_status

[shiyuhang0]

What problem does this PR solve?

Issue Number: close#757

Problem Description: TBD

What is changed and how does it work?

tikv/client-go#777

1. set VerifyIsPrimary to true for KvCheckTxnStatus RPC in client-java. TiKV will check if the primary lock is actually the primary. If not, it will not resolve the primary lock and throw a primaryMismatch error.
2. Judge primaryMismatch for PessimisticLock and resolve this PessimisticLock in client-java.
3. As for the primaryMismatch for non-PessimisticLock, TiKV will handle it and it will not happen in the client. If we meet it, just throw an exception.

TODO

1. add a test for this PR.
2. test if it works with lower version TiKV
