MPLS infrastructure improvments
- deprecate MPLSoEth and MPLSoGRE; replace with generic MPLS tunnel.
- deprecates CLI 'mpls encap ..'; replace with addition of MPLS out label to a route/tunnel.
- support for MPLS 'routes', e.g. MPLS x-connects.
- deprecates CLI 'mpls decap ..'; replace with 'mpls route .. '
