Add sample optimized for ramen test environment

This VM can be used to test DR flows in ramen minikube based test
environment running on a laptop.

Changes:
- Use latest cirros (0.6.2) from my repo that will be customized for
  testing ramen[2]
- Use executable userData since cirros does not support #cloud-config
- Inject ssh public key from secret
- Storage class used by ramen test environment
- Use bridge interface (see issue[1])
- Separate pvc and source resources
- Minimize memory allocation and disk size to make it easier to run with
  limited resources
- Use common labels to apply appname= label to all resources
