DaemonSet for all-in-one

[jpkrohling]

During the review of #75, it has been suggested that the all-in-one template could also be deployed as a DaemonSet. As this is "all-in-one", it would require the single pod to run as DaemonSet.

This issue is to gather thoughts and suggestions.

The reason I asked for this is to simplify migration from all-in-one to production deployment.
