ingress: Add option to assign VIP as externalIP

Some CNIs support the advertisement of service IPs into BGP, which may
provide an alternative to managing the VIP as an interface on the host.

This change adds an option to assign the ingress VIP as an externalIP to
the ingress service. For example:

    network:
      vip:
        manage: false
        addr: 172.18.0.1/32           # (with or without subnet mask)
        assign_as_external_ip: true
