CloudWatch alarm is missing metrics: MetricDataQuery[] field

[sam-goodwin]

The CfnAlarm L1 resource is missing the metrics: MetricDataQuery[] field described here: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cw-alarm.html#cfn-cloudwatch-alarm-metrics

Current generated CfnAlarmProps interface:

/**
 * @link http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cw-alarm.html
 */
export interface CfnAlarmProps {
    comparisonOperator: string | cdk.Token;
    evaluationPeriods: number | cdk.Token;
    threshold: number | cdk.Token;
    actionsEnabled?: boolean | cdk.Token;
    alarmActions?: Array<string | cdk.Token> | cdk.Token;
    alarmDescription?: string | cdk.Token;
    alarmName?: string | cdk.Token;
    datapointsToAlarm?: number | cdk.Token;
    dimensions?: Array<CfnAlarm.DimensionProperty | cdk.Token> | cdk.Token;
    evaluateLowSampleCountPercentile?: string | cdk.Token;
    extendedStatistic?: string | cdk.Token;
    insufficientDataActions?: Array<string | cdk.Token> | cdk.Token;
    metricName?: string | cdk.Token;
    // Where is metrics?: MetricDataQuery[];
    namespace?: string | cdk.Token;
    okActions?: Array<string | cdk.Token> | cdk.Token;
    period?: number | cdk.Token;
    statistic?: string | cdk.Token;
    treatMissingData?: string | cdk.Token;
    unit?: string | cdk.Token;
}

This isn't an issue with the CDK, the definitions are missing from the specification: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-resource-specification.html

I'm running into this issue—getting this fixed until #1396 lands could unblock some use-cases.
