the unitless metrics are good because they are low overhead to measure, but in the case of rebalancing, the overhead does not matter. emit a metric value everytime partitions are assigned/revoked (and how often a callback decides to shutdown/create strategies as a result), and also emit a counter for how many partitions are being assigned
