Description

Currently, every NiFi upgrade in Homebrew causes all state to be lost and users must start over or manually migrate their repos and flow.

We should improve the homebrew formula to include files that will persist between versions and default to properties that preserve this. Homebrew's guidance on the subject can be found at https://github.com/Homebrew/brew/blob/master/docs/Formula-Cookbook.md#handling-files-that-should-persist-over-formula-upgrades.
