// Returns a list of Amazon Redshift parameter groups, including parameter groups
// you created and the default parameter group. For each parameter group, the
// response includes the parameter group name, description, and parameter group
// family name. You can optionally specify a name to retrieve the description of a
// specific parameter group. For more information about parameters and parameter
// groups, go to Amazon Redshift Parameter Groups
// (https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-parameter-groups.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 parameter groups
// 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
// parameter groups that have any combination of those values are returned. If both
// tag keys and values are omitted from the request, parameter groups are returned
// regardless of whether they have tag keys or values associated with them.
