Please note that https://github.com/istio/istio/pull/40684 is in WIP as a corresponding implementation of this PR.

The port number 15004 is not used currently. But, if we need to keep it, I can support 15004 as well for keeping compatibility. @howardjohn what do you think?

To give some transition periods for "just-in-case", `15004` port also serves the debugging interface. 15004 port can be disabled by setting `PROXY_XDS_DEBUG_VIA_AGENT_PORT=0`.

https://github.com/istio/istio/pull/40687 would be another way to resolve the dependency cycle issue instead of refactoring "server.go". @howardjohn Can I get your opinion?
