Add liveness and readiness probes to the Kuryr controller
In order for the Kuryr controller to run well as a Pod, it is important that we add both readiness and liveness probes so that:
- Kubernetes can restart the controller if it gets to a broken state
- Kubernetes and its users know when the Kuryr Controller is ready to do its networking tasks
This blueprint calls for the addition of some REST endpoints to the kuryr-controller:
- /health/keystone: Able to authenticate with keystone
- /health/neutron: Able to talk to Neutron
- /health/k8s: Able to watch Kubernetes API
Then it is about creating a sample pod definition for the controller that includes both readiness probes[0] and liveness probes[1] for the endpoints above.
