(aws-appsync): Add Enhanced Metrics configuration to CDK

[piotrmoszkowicz]

Describe the feature

AWS AppSync some time ago introduced enhanced monitoring (https://docs.aws.amazon.com/appsync/latest/devguide/monitoring.html -> Enhanced Metrics), which allows to collect metrics at resolver/operation/data source leve. It is added within the CloudFormation (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-appsync-graphqlapi.html -> EnhancedMetricsConfig), so I think it would be great feature within CDK. I will be happy to implement it, maybe even within end of the week ;)

Use Case

Ability to configure AWS AppSync with Enhanced Monitoring.

Proposed Solution

Add missing property to AppSync's L2 construct and map it properly to AWS CloudFormation.

Hi @piotrmoszkowicz , thanks for requesting this feature and agreeing to volunteer for L2 contruct PR. It would be a helpful feature and there is already needed support by cloudformation. So please go ahead and feel free to submit the PR.
