  /**
   * The target state of a connector is its desired state as indicated by the user
   * through interaction with the REST API. When a connector is first created, its
   * target state is "STARTED." This does not mean it has actually started, just that
   * the Connect framework will attempt to start it after its tasks have been assigned.
   * After the connector has been paused, the target state will change to PAUSED,
   * and all the tasks will stop doing work. A target state of STOPPED is similar to
   * PAUSED, but is also accompanied by a full shutdown of the connector's tasks,
   * including deallocation of any Kafka clients, SMTs, and other resources brought
   * up for or by that task.
   * <p>
   * Target states are persisted in the config topic, which is read by all of the
   * workers in the group. When a worker sees a new target state for a connector which
   * is running, it will transition any tasks which it owns (i.e. which have been
   * assigned to it by the leader) into the desired target state. Upon completion of
   * a task rebalance, the worker will start the task in the last known target state.
