Separate the endpoints under app and management ports

[rverma-dev]

When we write an app in springboot we have a practice of exposing actuator (spring's health, readiness, version etc... APIs) under a separate port and actual api layer endpoints on entirely separate ports.

This also allow us to create better network policies too.

We do expose the metrics on a different port, we could add the probes handles there too.
