public final OperationCallable<CreateExternalAddressRequest, ExternalAddress, OperationMetadata>
      createExternalAddressOperationCallable() {

  }
Creates a new `ExternalAddress` resource in a given private cloud. The network policy that
corresponds to the private cloud must have the external IP address network service enabled
(`NetworkPolicy.external_ip`).
