Pulling consumers does not support DeliverGroup

[yang-xiaodong]

I see that push-based consumers are not currently supported, and I was wondering if pull-based consumers support DeliverGroup for effects similar to Kafka Consumer Groups (A event sent to multiple groups, with load balancing of consumers within groups).

thanks for bringing this up @yang-xiaodong we are missing pull consumer implementation we should implement them eventually. up to now we said we wouldn't have to expose the internals of consumer mechanics but this is a good example that we have to expose push consumers.
