[Exchange channels] enable consumer filters

[GuillaumeDSM]

For now it's impossible to specify a consumer filter when registering to an exchange channel:

    async def new_consumer(self,
                           callback: object = None,
                           consumer_filters: dict = None,
                           consumer_instance: object = None,
                           size=0,
                           symbol=CHANNEL_WILDCARD,
                           cryptocurrency=CHANNEL_WILDCARD):
        consumer = consumer_instance if consumer_instance else self.CONSUMER_CLASS(callback, size=size)
        await self._add_new_consumer_and_run(consumer,
                                             cryptocurrency=cryptocurrency,
                                             symbol=symbol,
                                             with_time_frame=self.WITH_TIME_FRAME)
        await self._check_producers_state()
        return consumer

consumer_filters is not taken into acount
