Switch to the new Telemetry API

[dasfmi]

AWS provides a new Lambda Telemetry API instead of the logs API and they recommend using the telemetry API moving forward.

Extensions can use the Telemetry API to subscribe to three different telemetry streams:

• Platform telemetry – Logs, metrics, and traces, which describe events and errors related to the execution environment runtime lifecycle, extension lifecycle, and function invocations.
• Function logs – Custom logs that the Lambda function code generates.
• Extension logs – Custom logs that the Lambda extension code generates.

This PR provides implementation for the new API, without parsing any messages!.
