(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.

Appreciate your efforts @piotrmoszkowicz . Team would be reviewing it.

Hey! Can we start looking at the code review for the PR? We would like to use that one in production and it is already stable for 3 weeks.

@piotrmoszkowicz , thanks for submitting the PR. I see that integ-test and snapshots needs to be added to the PR. Once those are added, a community reviewer will start the initial review followed by the maintainer review. If you need any help or guidance, please feel free to reach out on #contributing channel on cdk.dev slack.

Can you please merge in this PR? It was automatically closed. The enhanced metrics cannot be configured via CDK, although they were released 7 months ago.

Any update on this? Was looking to migrate an existing cloudformation template to CDK but am blocked because my appsync instance has this config and the EnhancedMetricsConfig property is not recognized

@xerebz @travishaby , the PR can not be merged until the integration test and snapshots are provided. #29940
