Description

Feature Overview

Use common HTTP/2 code for the HTTP/2 server, HTTP/2 proxy, and GRPC.

Alternatives Considered

Continue having lots of duplicate code, which makes maintenance more difficult

Additional Context

The large amount of duplicate code means that bugs will need to be fixed in multiple places and new features are much harder to add.

Contributor guide

Research direction
Identify duplicate HTTP/2 code in server, proxy, and gRPC implementations. Design a common module or functions to share the code. Ensure backward compatibility and no performance regression.
