kraken doesn't appear to respect kubeconfig_path in config.yaml

[Steve Ovens]

I recently attempted to setup Kraken in an Openshift 4.10.x cluster. Following the instructions I created a kubeconfig cm like so:

oc create configmap kube-config --from-file=/home/ocp/vmware-temp/auth/kubeconfig

This created a cm which had:

data:
  kubeconfig:

Thus rendering the file to /root/.kube/kubeconfig. Realizing this I edited the config.yaml file so that the top of the file looks like this:

kraken:
    distribution: openshift                                # Distribution can be kubernetes or openshift
    kubeconfig_path: /root/.kube/kubeconfig                        # Path to kubeconfig

This caused the pods to crash:

After speaking with @paigerube14 I tried editing the kubeconfig cm so that it read

data:
  config:

And then changed the path in the config.yaml so the path was /root/.kube/config and the pods started working.

The actual data inside the kube-config cm remained unedited. Only the heading (file name) changed.

I am unsure what caused this problem but it definitely seems like a bug
