Title: Emit metadata with username after successfully authenticated

Description: Once a request has been successfully authenticated using the BasicAuth filter, emit metadata containing username. The username can be used by the subsequent filters, such as the RBAC filter for authz.

Contributor guide

Research direction
Study the BasicAuth filter implementation in Envoy, specifically the authentication success path, and understand how to emit metadata using the filter callbacks. Look at existing filters that emit metadata for reference.
