This will allow us to dynamically track routes being added and removed, similar to what we do for IP addresses. 1. Support removing routes. Since this is a new function, we don't need to jump through hoops to support callers passing in routes that have no interface, we just fail to match them. 2. Make the addRoute method return a boolean value indicating whether anything changed. This is consistent with what we do for addresses and is used to decide whether to update the rest of the system when an update comes in.
