Description
This PR significantly improves the observability and reliability of the Feast Go Feature Server by implementing comprehensive Prometheus metrics, and robust configuration options for both HTTP and gRPC modes. It addresses issues with hardcoded ports, inconsistent metric exposure, and potential race conditions during shutdown.
Changes

Why gotoprom
It reduces boilerplate code for histograms and ensures type-safety for labels, preventing runtime panics due to mismatched label cardinality. It wraps the official prometheus client, so it's fully compatible
