// Returns a database user name and temporary password with temporary authorization

// name prefixed with IAM: if AutoCreate is False or IAMA: if AutoCreate is True.
// You can optionally specify one or more database user groups that the user will
// join at log on. By default, the temporary credentials expire in 900 seconds. You
// can optionally specify a duration between 900 seconds (15 minutes) and 3600
// seconds (60 minutes). For more information, see Using IAM Authentication to
// Generate Database User Credentials
// (https://docs.aws.amazon.com/redshift/latest/mgmt/generating-user-credentials.html)
// in the Amazon Redshift Cluster Management Guide. The Identity and Access
// Management (IAM) user or role that runs GetClusterCredentials must have an IAM
// policy attached that allows access to all necessary actions and resources. For
// more information about permissions, see Resource Policies for
// GetClusterCredentials
// (https://docs.aws.amazon.com/redshift/latest/mgmt/redshift-iam-access-control-identity-based.html#redshift-policy-resources.getclustercredentials-resources)
// in the Amazon Redshift Cluster Management Guide. If the DbGroups parameter is
// specified, the IAM policy must allow the redshift:JoinGroup action with access
// to the listed dbgroups. In addition, if the AutoCreate parameter is set to True,
// then the policy must include the redshift:CreateClusterUser privilege. If the
// DbName parameter is specified, the IAM policy must allow access to the resource
