Produce message using REST API through Proxy

[thomaeschen]

Is your enhancement request related to a problem? Please describe. Since Pulsar 2.9.X, the pulsar system is able to produce message directly to the broker from the REST client. It is more convenient and safety to let the user to produce the message using REST client to the proxy instead directly to the broker.

Describe the solution you'd like The REST client could send the message to the proxy and the proxy redirect the request to the broker to produce a message

Describe alternatives you've considered

1. Create a reverse proxy in the K8s to redirect the message from outside to the broker-service which is inside the k8s
2. Expose the broker URL to the outside of the k8s
