K8sAutoscaleNode and Openshift

Kapacitor 1.4.0
Openshift 3.7

Im trying to get the K8sAutoscaleNode to work with Openshift and Im running into a strange issue.

```
|k8sAutoscale()
.kind('deployments')
.namespace('testproj')
.resourceName('test')
.increaseCooldown(increase_cooldown)
.decreaseCooldown(decrease_cooldown)
.replicas(lambda: int(ceil("avg_workers" / target)))
```

In the logs Im getting the following.

`ts=2018-02-22T16:51:40.007+01:00 lvl=error msg="error handling point" service=kapacitor task_master=main task=autoscaler node=k8s_autoscale5 err="could not determine initial scale for \"testproj/deployments/test\": failed to get scale testproj/deployments/test: failed to understand k8s server response: Code: 403: invalid character 'U' looking for beginning of value"
`

It looks like it picks up all the k8s info that it needs but it's getting something strange back.
Tried all different .kind settings, not getting any progress though.

Any ideas?

Start at the K8sAutoscaleNode entry point and reproduce the issue against the stated Kapacitor 1.4.0 and OpenShift 3.7 setup. Inspect the 403 response and determine whether the failure is caused by authentication or API compatibility; done means documenting or fixing the supported behavior.
