Add liveness/readiness endpoints

These endpoints are used to test for the liveness and readiness of the
application in Kubernetes.

This allows the application to take its time to startup, set the
liveness and readiness endpoints as ready, then begin to accept
requests.

The endpoints are:
- /q/health/live
- /q/health/ready
