* fix: using relay without bcaster should consume and drop messages * update relay api usage * move subscription to broadcaster * move filter logic under subscription * Support more than 1 relay subscription for a pubSubTopic * modify relay Publish API to derive pubSubTopic based on autosharding * implement relay RPC methods for autosharding * remove relay msgChannel and relay on pubsub buffersize for subscription Co-authored-by: richΛrd <info@richardramos.me> * handle relay subscribe with noConsumer and address issue reported in code review * chore: reorg relay code --------- Co-authored-by: richΛrd <info@richardramos.me>
