We're moving our observability suite to Core

What this post added

This post announces the migration of GitLab's observability suite (custom metrics, logging, tracing, and alerting) from proprietary code to the open-source Core product. It outlines the rationale behind this move, emphasizing stewardship, the fundamental nature of observability for developers, and the desire for community input. Specific areas for potential contribution include enhancing custom metrics integration with Prometheus, innovating log tailing capabilities, and deepening the integration of Jaeger for tracing and alerting. The post also touches on closing the DevOps loop by integrating alerting with incident management issues.
