Handle port reachability group

Summary:
Program reachability group ID on port, if port has intended value.

The programming model goes as followed -
1. NOS programs switch attribute reachability group list, to indicate the total amount of reachability group.
2. For each port, program the attribute of reachability group, to indicate which group it belongs to.
