CloudFormation suppoert for IoT SiteWise Asset model components

Looking at the documentation, we do support Asset Model Components ( not sure when the feature was added to cloudformation). When leveraging cloudformation to create an asset model component, you have to declare the entity of type AWS::IoTSiteWise::AssetModel and define the AssetModelType properties as Component Model. This is documented here: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-iotsitewise-assetmodel.html#cfn-iotsitewise-assetmodel-assetmodeltype

Additionally for resources that are not supported by cloudformation yet, you could open a issue within our github project aws-cloudformation/cloudformation-coverage-roadmap to be reviewed by our service team and add to roadmap.
