Retrieves the specified alarms. You can filter the results by specifying a prefix for the alarm name, the alarm state, or a prefix for any action.
            To use this operation and return information about composite alarms, you must be signed
            on with the cloudwatch:DescribeAlarms permission that is scoped to *.
            You can't return information about composite alarms if your cloudwatch:DescribeAlarms
            permission has a narrower scope.
            
For .NET Core this operation is only available in asynchronous form. Please refer to DescribeAlarmsAsync.
