BREAKING CHANGES

• lambda: cloudWatchLogsRetentionTimeDays in @aws-cdk/aws-cloudtrail
  now uses a logs.RetentionDays instead of a LogRetention.
• core: stack._toCloudFormation method is now unavailable and is replaced by @aws-cdk/assert.SynthUtils.toCloudFormation(stack).
• rds: replaced kmsKeyArn: string by kmsKey: kms.IEncryptionKey in DatabaseClusterProps
• autoscaling: VpcNetwork.isPublicSubnet() has been renamed to
  VpcNetwork.isPublicSubnetIds().
• serverless: renamed aws-serverless to aws-sam
• ec2: vpcPlacement has been renamed to vpcSubnets
  on all objects, subnetsToUse has been renamed to subnetType.
  natGatewayPlacement has been renamed to natGatewaySubnets.
• All properties of all structs (interfaces that do not begin with an "I") are now readonly since it is passed by-value and not by-ref (Python is the first language to require that). This may impact code in all languages that assumed it is possible to mutate these structs. Let us know if this blocks you in any way.
