KUDU-2612: acquire and release partition lock

This patch introduces the logic for actual acquiring and releasing
the partition lock for transactions and non-transactional operations.
For each transaction, we try to acquire the partition lock in the
ParticipantOp prepare phase of BEGIN_TXN and release the lock when
COMMIT_TXN or ABORT_TXN is applied. Moreover, we take the parition
lock for non-transactional operations as well to ensure we don’t
have duplicate keys. If the partition lock cannot be acquired,
the transaction (or write op) will be aborted or retried.
