      Description

      Currently the only way to explicitly trigger a rebalance is by unsubscribing the consumer. This has two drawbacks: it does not work with static membership, and it causes the consumer to revoke all its currently owned partitions. Streams relies on being able to enforce a rebalance for its version probing upgrade protocol and the upcoming KIP-441, both of which should be able to work with static membership and be able to leverage the improvements of KIP-429 to no longer revoke all owned partitions.

      We should add an API that will allow users to explicitly trigger a rebalance without going through #unsubscribe
