[feat] Allow Pulsar Proxy-to-Pulsar Proxy communication before reaching broker #24891
Description

- I searched in the issues and found nothing similar.
Motivation
In some deployment scenarios, it's useful for one proxy to connect through another proxy before reaching the broker. The first proxy may not necessarily be a standard Pulsar Proxy, but as long as it follows the Pulsar protocol rules, the downstream proxy should be able to communicate with it seamlessly.
Supporting this “proxy-to-proxy” connection improves flexibility for complex network topologies, including multi-region deployments, edge-to-central routing, or hierarchical proxy layers. It ensures that authentication, routing, and protocol rules continue to work correctly, even when traffic passes through multiple proxies before reaching the broker.
