// Creates a new DB parameter group. A DB parameter group is initially created
// with the default parameters for the database engine used by the DB instance. To
// provide custom values for any of the parameters, you must modify the group after
// creating it using ModifyDBParameterGroup. Once you've created a DB parameter
// group, you need to associate it with your DB instance using ModifyDBInstance.
// When you associate a new DB parameter group with a running DB instance, you need
// to reboot the DB instance without failover for the new DB parameter group and
// associated settings to take effect. After you create a DB parameter group, you
// should wait at least 5 minutes before creating your first DB instance that uses
// that DB parameter group as the default parameter group. This allows Amazon
// Neptune to fully complete the create action before the parameter group is used
// as the default for a new DB instance. This is especially important for
// parameters that are critical when creating the default database for a DB
// instance, such as the character set for the default database defined by the
// character_set_database parameter. You can use the Parameter Groups option of the
// Amazon Neptune console or the DescribeDBParameters command to verify that your
// DB parameter group has been created or modified.
