Bug 7106: Handles static routes at InterVpnLink creation

 + When an InterVpnLink is created it is possible that there are
   some static routes pointing to any of the InterVpnLink endpoints.
   This could happen if, for example, an InterVpnLink is removed and
   created again after some time.

 + So, at InterVpnLink creation, it'll check all Neutron routers to see
   if any of them has an static route whose nexthop is one of the
   InterVpnLink endpoints. If so, the static route must be 'installed'
   in the DPN where the corresponding Endpoint has been instantiated.

 + There is a bit of refactoring. Code that was in VpnRpcServiceImpl has
   been extracted to InterVpnLinkUtils so that it can be reused.

 + InterVpnLinkCache is now created at InterVpnLinkListener creation
