…also clear the running assignment (#8804) Until recently revocation of connectors and tasks was the result of a rebalance that contained a new assignment. Therefore the view of the running assignment was kept consistent outside the call to `RebalanceListener#onRevoke`. However, after KAFKA-9184 the need appeared for the worker to revoke tasks voluntarily and proactively without having received a new assignment. This commit will allow the worker to restart tasks that have been stopped as a result of voluntary revocation after a rebalance reassigns these tasks to the work. The fix is tested by extending an existing integration test. Reviewers: Randall Hauch <rhauch@gmail.com>

Until recently revocation of connectors and tasks was the result of a rebalance that contained a new assignment. Therefore the view of the running assignment was kept consistent outside the call to
RebalanceListener#onRevoke. However, after KAFKA-9184 the need appeared for the worker to revoke tasks voluntarily and proactively without having received a new assignment.This commit will allow the worker to restart tasks that have been stopped as a result of voluntary revocation after a rebalance reassigns these tasks to the work.
The fix is tested with an integration test but we should consider adding coordinator tests that now that the logic of the worker coordinator includes revocation of tasks.
