anand76 18a3227b12 Add a new IOStatus subcode to indicate that writes are fenced off (#7374) ... Summary: In a distributed file system, directory ownership is enforced by fencing off the previous owner once they've been preempted by a new owner. This PR adds a IOStatus subcode for ```StatusCode::IOError``` to indicate this. Once this error is returned for a file write, the DB is put in read-only mode and not allowed to resume in read-write mode.
