[New Orb] Swissknife - monorepo helper & more

Hey folks,

I’ve been working on an orb which helps with various tasks that one needs to do in a monorepo setting: https://circleci.com/orbs/registry/orb/roopakv/swissknife

There are also some commands that help do things that are not easily possible with circle right now.
e.g. queue up workflows so only one runs at a time. Granted this isnt done in a very optimal manner, but hey it works :slight_smile:

I’d love feature requests / feedback on what else would be useful to folks.
