GH-3307: Retry TransTimedEx in LockRepo.acquire

Fixes #3307

The `DefaultLockRepository.acquire()` is transactional method and
can fail with the `TransactionTimedOutException`.
When we call `JdbcLock.lock()`, we expect an attempt until we really obtain a lock.

* Treat a `TransactionTimedOutException` as a `TransientDataAccessException` and 
therefore retry a locking attempt logic

**Cherry-pick to 5.3.x, 5.2.x & 4.3.x**
