 Description   

Currently, there is no limit to the number of chunks that can be squashed together during an auto-merging round. This implies that it is possible to auto merge hundreds of thousand of chunks in one shot causing a relevant stall on the next routing table refresh.

Purpose of this ticket is to limit the amount of chunks that can be merged in one shot and to return to the balancer the number of chunks that were merged
