(cloudfront): support gRPC config for distribution

[go-to-k]

Describe the feature

CloudFormation supports GrpcConfig property to enable gRPC in CacheBehavior and DefaultCacheBehavior.

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-grpcconfig.html

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-cachebehavior.html

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-defaultcachebehavior.html

So it would be good to enable gRPC for CloudFront Distribution using L2.

Use Case

Amazon CloudFront supports gRPC, an open-source remote procedure call (RPC) framework built on HTTP/2. gRPC offers bi-directional streaming and binary protocol that buffers payloads, making it suitable for applications that require low latency communications.

Proposed Solution

Add the property like enableGrpc for behavior option.

The support for GrpcConfig property in CacheBehavior and DefaultCacheBehavior was added 4 days ago via commit https://github.com/cdklabs/awscdk-service-spec/commit/0ffd16642fbb1067754c1fc9306bf985a18daa69/ in latest https://github.com/cdklabs/awscdk-service-spec/blob/main/sources/CloudFormationSchema/us-east-1/aws-cloudfront-distribution.json.

This property is yet to be available in L1 CfnDistribution.CacheBehaviorProperty as of now.

The PR #32540 that updates L1 CloudFormation resource definitions, was merged 4 hours ago. It also added GrpcConfig property per description:
