Wrap Zookeeper probe script with timeout command (#214)

Browse Source 
so that the probe doesn't continue running indefinitely

- resolves the issue with Kubernetes <1.20
  "Before Kubernetes 1.20, the field timeoutSeconds was not respected for exec probes:
    probes continued running indefinitely, even past their configured deadline,
    until a result was returned."
    in https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes

- #179 already fixed the issue for Kubernetes 1.20+
