Feature Request: "reachable" binary sensor for port(s).

[GuruSR]

Under "show load-balance status", the ports will have a "reachable" entry that will either be true/false. It also has a "status" for active/inactive (but that is more confusing since you already have a status), but the "reachable" state means the connection is working, if not, no data is passing back and forth. Very handy since the built in interface neglects to show this.
