    Do not try to call status setting methods in case of periodic task

    [0] enhanced the failure handling of taas agent, but the handling of
    periodic_task was left out, which resulted in exceptions:
    KeyError: 'periodic_tasks'.
    To avoid such exception TaasAgentRpcCallback's self.func_dict must be
    extended with periodic_task entry.
