@drivebyer this seems to be invalid as probes require a handler: can you confirm your intent?

I can't deploy with the webhook enabled. Seems like it's due to this.

Error: 1 error occurred:
* Deployment.apps "redis-operator" is invalid: [spec.template.spec.containers[0].livenessProbe: Required value: must specify a handler type, spec.template.spec.containers[0].readinessProbe: Required value: must specify a handler type]

redisOperator:
  webhook: true
