I think the new property is overkill and agree with @MikeThomsen that
correcting the typo should not impact many users in any serious fashion. If we
don't want to impact anyone and keep the current UX, then since this is just a
machine-friendly name not exposed to the user, I think we could just target
this PR for NiFi 2.0---
