Support pause/resume of consumer

[JackMF]

Is it possible to support this feature here? Is there a road map for other features?

Hello,

There is no roadmap for any new feature. Any PR is welcome. I usually implemented the features I'm using in our applications.

Hey see this WIP MR to support pause and resuming of consumers: #35

This idea here is to turn the cosnumer into a genstate_m and have a "paused" state and a "polling" state.

Let me know what you think about this approach @silviucpp and I will continue to with the requried changes to -erlkaf_consumer_group and erlkaf_manager so that pasue and resume can be called by the api.
