      Allows Egress from pods labeled with 'networking.gardener.cloud/to-public-networks=allowed'
      to all Public network IPs, except for
      - Private networks (RFC1918)
      - Carrier-grade NAT (RFC6598)
      - CloudProvider's specific metadata service IP.

      In practice, this blocks Egress traffic to all networks in the Seed cluster and only traffic to
      public IPv4 addresses.
