Implement Route Table with ip address next hop

[Sachin Bansal]

Currently, we have an implementation of route tables where each route can have a service instance as a next hop. We need to be able to specify an ip address as next hop. For this, I propose to change the next-hop-type field in RouteType to an enum with two possible values: 'service-instance' and 'ip-address'. If the field is not set, we will treat it same as 'service-instance'. If it is set to 'ip-address', the next hop must be a valid ip address. We will then create a static-route in the primary routing instance of that network with the same prefix and next hop and no route targets.

Highlights:

- Fix bug wherein an empty route target list for a static route caused
it to not have any tunnel encap, security groups etc.
- Set the OriginVn for static routes if the route target list is empty
- Update all static routes for a routing instance when vn index changes
- Add unit and integration tests
