Use a DaemonSet instead of a Deployment to deploy our app

- For high availability reasons, we would like our app to scale linearly
  with the size of the control plane. Using a DaemonSet allows us to run
  one pod on each node-role.kubernetes.io/master node.
- The hope is that the Service that we create should load balance
  between these pods appropriately.
