Deployment Prefix not working

[inteon]

I tried the deployment prefix feature, but it does not seem to work (prefixes are not added to the deployment names).
See cbbc833#r52391721 for more info.

I'll check this out, thank you!

This tool would be helpful in my case because my minikube startup script needs to wait for cert-manager before running helm upgrade on the chart that depends on cert-manager, but I'm unable to use cm-verify because the --prefix option does not work.
