-- | 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 'rebooting'. A cluster event is created when the reboot is completed. Any pending
-- cluster modifications (see 'ModifyCluster') are applied at this reboot. For
-- more information about managing clusters, go to <http://docs.aws.amazon.com/redshift/latest/mgmt/working-with-clusters.html Amazon Redshift Clusters> in
-- the /Amazon Redshift Cluster Management Guide/
