Recommended fix

Ran into this when trying to ship Kubernetes logs on the newest version. I had to make a couple small changes the logzio-daemonset.yml file to successfully ship.

Change apiVersion: extensions/v1beta1 to apiVersion: apps/v1

and add the following object to spec:

selector:
  matchLabels:
    k8s-app: fluentd-logzio
    version: v1

@imnotashrimp I thought we fixed it and it turns out we did at #39
