Remove the gateway check for routes (#1317)

Browse Source 
Most operating systems add a /32 route for the default gateway address to its routing table

This will allow routes to be configured into the system even when the incoming range contains the default gateway.

In case a range is a sub-range of an existing route and this range happens to contain the default gateway it attempts to create a default gateway route to prevent loop issues
