Add --volumes parameter, deprecate emptyvols

This adds the --volumes paramater with a "generate" and "empty"

By default, "generate" will be used as a place-holder for "true".
Although not used in the code, we will eventually add "none"

This uses CLI paramater naming processes (no emptyVols as that is Go /
Kubernetes specific) and thus we use dashes.
