Reboots a cluster. This action is taken as soon as possible. It results in a momentary outage to the cluster, during which the cluster status is set to <code>rebooting</code>. A cluster event is created when the reboot is completed. Any pending cluster modifications (see <a>ModifyCluster</a>) are applied at this reboot. For more information about managing clusters, go to <a href="https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-clusters.html">Amazon Redshift Clusters</a> in the <i>Amazon Redshift Cluster Management Guide</i>.
