i dont think we should commit this into the codebase. It could be fine to
publish the bash script in the wiki page associated with release
guide/validation. We must also be clear this is good for things which are
easily automated such as verification of sigs/hashes/build but for other things
like actually testing nifi and the hard work of L&N review its an eyes-on game.---
