DHCPv[46] relay must replace the route instead of adding an extra NH
Currently DHCP relay adds an extra next-hop to an already existing route (if any). Instead
it must replace it with the new one.
This patch adds replaceRoute method to the RouteStore interface and corresponding implementations.
The DHCP relay implementation uses the new method instead of updateRoute
