sticky consumer: how to grab a consumer by its groupId

[adam-thibodeaux]

need to create a method for killing all consumers on key=kill message one consumer 'sticks' to the topic, new consumers don't displace how do we grab a consumer by its groupId?

[shamilahfaria]

old consumer is attached to topic and being read new consumer can't be attached to topic because old consumer is on it. but info is still being sent to aws ? regardless of which consumer it is? so it doesn't matter for functional purposes, just testing purposes.
