 Description   

This spec http://specs.openstack.org/openstack/neutron-specs/specs/api/extra_routes.html adds support for adding static routes to a router object. This is supported in ODL_L3 plugin also. But these routes are not stored by NeutronNorthbound in MDSAL.

Steps to reproduce:
-------------------
1. Create neutron network, subnet and router and add interface in that subnet to router.
2. Add extra routes to router:
neutron router-update myrouter --routes type=dict list=true destination=100.0.0.0/24,nexthop=11.11.11.8

Expected behavior:
------------------
A get on MDSAL show show routes added to MDSAL.

Actual behavior:
----------------
stack@liberty-osc:~/devstack$ neutron router-show myrouter
-------------------------------------------------------------------------------+

Field Value

-------------------------------------------------------------------------------+

admin_state_up True
distributed False
external_gateway_info  
id d74a39ab-da42-4a27-bd3a-701a16f0955a
name myrouter
routes {"destination": "100.0.0.0/24", "nexthop": "11.11.11.8"}
status ACTIVE
tenant_id ba37d16d954f4e16bc5b6c78e41f55a5

-------------------------------------------------------------------------------+

Routes are not added to MDSAL:
{
"routers": [

{ "admin_state_up": true, "distributed": false, "external_gateway_info": null, "gw_port_id": null, "id": "d74a39ab-da42-4a27-bd3a-701a16f0955a", "name": "myrouter", "routes": [ "" ], "tenant_id": "ba37d16d954f4e16bc5b6c78e41f55a5" }

]
}

According to the neutron API, the yang model itself is wrong.

This also needs https://git.opendaylight.org/gerrit/#/c/33919/ for OVSDB.
