// Returns properties of provisioned clusters including general cluster properties,

// and access properties. This operation supports pagination. For more information
// about managing clusters, go to Amazon Redshift Clusters (https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-clusters.html)
// in the Amazon Redshift Cluster Management Guide.
//
// If you specify both tag keys and tag values in the same request, Amazon Redshift
// returns all clusters that match any combination of the specified keys and
// values. For example, if you have owner and environment for tag keys, and
// admin and test for tag values, all clusters that have any combination of
// those values are returned.
//
// If both tag keys and values are omitted from the request, clusters are returned
// regardless of whether they have tag keys or values associated with them.
