Rodolfo Alonso Hernandez 5fb5653ffe Check router routes connectivity when GW port is updated
When the router GW interface is updated or deleted, the routes should
be checked in other to prove all of them have connectivity to any of
the router interface subnets.

In a router, all routes nexthops must have connectivity with one
interface subnet. If not, this route cannot send the packets to this
route gateway; therefore this route becomes invalid.

Reject any router route or gateway update if not all route nexthops have
connectivity with any gateway subnets CIDRs; in other words, all route
nexthops IP addresses should belong to one gateway subnet CIDR.
