What does your PR do?

The current scheduler health check includes python code that changes with Airflow version and with the recent 2.6.0 release there are more changes needed to the health check code.

Instead scheduler exposes a webserver that runs the exact same health check code and is maintained along with Airflow code. This change leverages the same webserver to perform readiness and liveness probes.
