// 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.
