Subject: [PATCH] Increase transaction timeout and enable deadlock detection in
 stress test (#7056)

There are errors like `Transaction put: Operation timed out: Timeout waiting to lock key
terminate called without an active exception`, based on experiment on devserver, increasing timeouts can resolve the issue.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/7056
