Description

The log_duration parameter must be defined in the parameters array of alicloud_db_instance resources and set to ON.
If log_duration exists and is set to OFF, the rule reports an IncorrectValue issue and suggests replacing OFF with ON.
If the parameters array or the log_duration parameter is missing, the rule reports a MissingAttribute issue and suggests adding parameters = [{ name = "log_duration" value = "ON" }].
