// DeleteAlarmsRequest returns a request value for making API operation for
// Amazon CloudWatch.
//
// Deletes the specified alarms. You can delete up to 100 alarms in one operation.
// However, this total can include no more than one composite alarm. For example,
// you could delete 99 metric alarms and one composite alarms with one operation,
// but you can't delete two composite alarms with one operation.
//
// In the event of an error, no alarms are deleted.
//
// It is possible to create a loop or cycle of composite alarms, where composite
// alarm A depends on composite alarm B, and composite alarm B also depends
// on composite alarm A. In this scenario, you can't delete any composite alarm
// that is part of the cycle because there is always still a composite alarm
// that depends on that alarm that you want to delete.
//
// To get out of such a situation, you must break the cycle by changing the
// rule of one of the composite alarms in the cycle to remove a dependency that
// creates the cycle. The simplest change to make to break a cycle is to change
// the AlarmRule of one of the alarms to False.
//
// Additionally, the evaluation of composite alarms stops if CloudWatch detects
// a cycle in the evaluation path.
//
//    // Example sending a request using DeleteAlarmsRequest.

//    resp, err := req.Send(context.TODO())
