def diag_network(self, *args, **kwargs):
raise NotImplementedError('<STR_LIT>'<EOL>'<STR_LIT>')<EOL>
Diagnose a network.

        :raises NotImplementedError: This driver does not manage networks.

        NOTE: This is a no-op in the base driver, but this raises here as to
        explicitly disallow network operations in case of a misconfiguration.
