Openstack Ephemeral Configuration File Definition
-----------------------------------------------------
The Openstack Bootstrap container creates an Ephemeral K8S cluster on the Openstack.
The container requires clouds.yaml credentials and other information about the cluster to deploy.
It requires a YAML configuration file with the format provided below.

<Openstack Config Definition>
apiVersion: v1
kind: OpenstackConfig
metadata:
  name: <metadata-name>
credentials:
  credential: <Clouds.yaml file of devstack>
  cloudName: <openstack cloud name i.e. devstack>
spec:
  cluster:
    machineSize: <Openstack VM flavor, e.g. ds2G>
    kubeconfig: <Kubeconfig filename, Default is 'kubeconfig'>
    securityGroup:<Security Group that'll be attached to the VM>
</Openstack Config Definition>

The expected location for the Openstack bootstrap configuration file is dictated by the "volume" mount
specified in the Airship config file (bootstrapInfo.ephemeral.container.volume).
For example, $HOME/.airship folder and shown in the snippet below:

<Snippet>
apiVersion: airshipit.org/v1alpha1
bootstrapInfo:
  ephemeral:
    container:
      volume: /home/stack/.airship:/kube
</Snippet>
