Break Step Runners out into their own files; create runners directory to contain them

[jrayback]

I think it would be much more readable to break the runners out into individual files and put them in a runners directory. Right now they are buried in a single obscurely named file in utils. This is. not easy to find for new users of the repo. What do you all think?

I agree @jrayback, sounds good to me.

@jrayback yes the team has discussed this. I've demonstrated it in this PR that will come out of draft soon. i had to keep the old big file since it continues to change but see https://github.com/GLEIF-IT/vlei-verifier-workflows/pull/27/files#diff-f0873745a37bd47ee1bdf49492633ff7da8194d725be20614854761d15fcc1bdR1
And see how i am using it in reg-pilot, although i need to refactor that into separate files after the vlei-verifier-workflows PR is merged https://github.com/GLEIF-IT/reg-pilot/pull/190/files#diff-8b8f632f8c07506d477d423d43a3102ef5c94993bb95a4bf2b352eb68fab689fR65

So, does that mean I should hold off? That you have it covered? @2byrds
