We're moving our observability suite to Core

This post announces the migration of observability features (custom metrics, logging, tracing, alerting) from a proprietary codebase to the open-source Core product. It outlines the rationale behind this move, emphasizing stewardship, the importance of observability for all developers, and the desire for community input. Specific areas for contribution include improving custom metrics integration with Prometheus, enhancing log tailing capabilities, and deepening the integration of Jaeger for tracing and alerting.
