  1. c/controller_backend: fix dispatching update finished command 

    Fixed dispatching update_finished command when no replicas were added to
the replica set.

Previously when no replicas were added to the replica set there was no
node that would pass the condition allowing it to dispatch update
finished command. This way partition reconfiguration never finished
causing chaos-tests to fail.

  3. tests/node_op_fuzzy: do not create/delete topics 

    As we are already using admin operations fuzzer to execute admin day-2
operations we may skip creating/deleting topics explicitly

  4. tests: added add no wait to nodes operations fuzzy test 

    Added `add_no_wait` operation to nodes operations fuzzy test. The add no
wait does not wait for the node to be populated with partitions before
executing next operation, this way we are giving decommissioning a
change to be executed before addition will be finished therefore
triggering move cancellation code path.
