/**
 * This method handles the transition from {@code Rebalancing} state.
 * It starts a periodic timer in order to check the status of the ongoing rebalance processing on Cruise Control side.
 * In order to do that, it calls the related Cruise Control REST API about asking the user task status.
 * When the rebalance is finished, the next state is {@code Ready}.
 * If the user sets the strimzi.io/rebalance annotation to 'stop', it calls the Cruise Control REST API for stopping the ongoing task
 * and then transitions to the {@code Stopped} state.
 * If the user sets any other values for the strimzi.io/rebalance annotation, it is just ignored and the user task checks continue.
 * This method holds the lock until the rebalance is finished, the ongoing task is stopped or any exception is raised.
 *
 * @param reconciliation Reconciliation information
