Added a route for health check

[nagn]

Problem

In Kubernetes running docker containers typically need a readiness and health checks to make sure the container is running/ready

Solution

Describe the modifications you've done. Added a path for /health that just returns 200 so the container can run in K8s.

Result

This will always return a passing health check so long as its running. Note that to truly follow k8s semantics we would probably want a seperate readiness check to pass (for instance once we've established a connection to redis), versus liveness which just checks that the service is alive. LMK if this is important enough to revise

@meyer thanks for running the checks! You'll have to merge it since I don't have write access but I appreciate you taking a look!
