Yingchun Lai e4dc2ec440 [StorageEngine] Make StorageEngine::open return more detailed info (#3761) 
StorageEngine::open just return a very vague status info when failed,
we have to check logs to find out the root reason, and it's not
convenient to check logs if we run unit tests in CI dockers.
It would be better to return more detailed failure info to point out
the root reason, for example, it may return error status with message
"file descriptors limit is too small".
