      - Addresses are restricted based on the forwarding rule's load balancing scheme
        (EXTERNAL or INTERNAL) and scope (global or regional).
      - When the load balancing scheme is EXTERNAL, for global forwarding rules, the
        address must be a global IP, and for regional forwarding rules, the address
        must live in the same region as the forwarding rule. If this field is empty,
        an ephemeral IPv4 address from the same scope (global or regional) will be
        assigned. A regional forwarding rule supports IPv4 only. A global forwarding
        rule supports either IPv4 or IPv6.
      - When the load balancing scheme is INTERNAL, this can only be an RFC 1918 IP
        address belonging to the network/subnet configured for the forwarding rule.
        By default, if this field is empty, an ephemeral internal IP address will
        be automatically allocated from the IP range of the subnet or network configured
        for this forwarding rule.

        xDS clients present node metadata. If a match takes place, the relevant routing
        configuration is made available to those proxies.
      - For each metadataFilter in this list, if its filterMatchCriteria is set to
        MATCH_ANY, at least one of the filterLabels must match the corresponding label
        provided in the metadata. If its filterMatchCriteria is set to MATCH_ALL,
        then all of its filterLabels must match with corresponding labels in the provided
        metadata.

        the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?`
