Summary: **Context:** We currently have partial error injection: - DB operation: all read, SST write - DB open: all read, SST write, all metadata write. This PR completes the error injection (with some limitations below): - DB operation & open: all read, all write, all metadata write, all metadata read **Summary:** - Inject retryable metadata read, metadata write error concerning directory (e.g, dir sync, ) or file metadata (e.g, name, size, file creation/deletion...) - Inject retryable errors to all major file types: random access file, sequential file, writable file - Allow db stress test operations to handle above injected errors gracefully without crashing - Change all error injection to thread-local implementation for easier disabling and enabling in the same thread. For example, we can control error handling thread to have no error injection. It's also cleaner in code. - Limitation: compared to before, we now don't have write fault injection for backup/restore CopyOrCreateFiles work threads since they use anonymous background threads as well as read injection for db open bg thread - Add a new flag to test error recovery without error injection so we can test the path where error recovery actually succeeds - Some Refactory & fix to db stress test framework (see PR review comments) - Fix some minor bugs surfaced (see PR review comments) - Limitation: had to disable backup restore with metadata read/write injection since it surfaces too many testing issues. Will add it back later to focus on surfacing actual code/internal bugs first.
