Unknown object type for es-curator, k8s 1.8

[z1nkum]

Hi,

I was surprised when trying create curator CronJob:

# kubectl create -f es-curator.yaml

error: error validating "es-curator.yaml": error validating data: unknown object type schema.GroupVersionKind{Group:"batch", Version:"v2alpha1", Kind:"CronJob"}; if you choose to ignore these errors, turn validation off with --validate=false

It's because of kubernetes/kubernetes#41039 - so, if you try it with 1.8, change

apiVersion: batch/v2alpha1 to apiVersion: batch/v1beta1

Good catch.
