Add HealthChecks for LPR_Service

[ksingh7]

Add health checks such that if app container id down, openshift try to restart that based on health checks

I have partially solved the going down issue by adding a try/except to the inference function so that it crashes "smoothly". Then uvicorn restarts the process properly.
It's a small patche for now, but yes, a small healthcheck endpoint would be good.
