Proposed changes

Added support for use different router IDs per VRF defined in network services.

vrfs:
      - name: myvrf
        bgp:
          # Router ID to use for BGP in this VRF.
          # This can be an IP address, "main_router_id", "none", "vtep_diagnostic"
          # - "use_main_router_id" will reuse the main BGP Router ID which is the IP address of Loopback0.
          # - "none" will not configure a BGP Router ID for this VRF. EOS will use the main BGP Router ID. <--- TODO: Verify this.
          # - "vtep_diagnostic" will use the IP address of the VRF Diagnostic Loopback interface.
          router_id: <str; default="main_router_id">
        ospf:
          router_id: <same>
