provide easy option for users in setup without PVs

[dustymabe]

If a user is targeting an env without PVs it would be great if we gave them an easy option for getting up and running. Rather than having them create PVs (which can be complicated or maybe even not allowed if they don't control their environment) I think we should give them the option --volume=empty to substitute in a emptyDir for a PVC. The --volume option would could default to --volume=pvc.

This would allow them to get going without having to have it all set up, but would keep sane defaults for people who have real environments with appropriate volume setups.

alternatively we could default to emptyDir and warn the user that if they want persistence they should provide --volume=pvc.

This is another thing that we might want to put in a preference file as well.

This is great idea. But I would keep --volume=pvc as default, because I think that emptyDir is dangerous for users that don't know how ti works.

cool - I assume we can plan on doing this then, unless someone else objects
