NewCDKClient creates a new component CDK client This client provides opinionated access to the services offerred from gRPC in the CDK (caching, metric data, etc) Note, ensure you are closing the gRPC connection when your component ends using the `Close()` method on the ComponentCDKClient.

MetricData is used when sending data to Honeycomb For convience, use the `Metric()` method on the ComponentCDKClient instead of this struct directly.
