scaffolding

@avnik Did some dumb polishing before merging, nothing worth to be discussed, just FYY:

• renamed your commits that weren't using conventional names (still unsure if it's a thing that we want though)
• realized that we weren't importing the shell module
• wrote a minimal README
• enable CI for x86_64-darwin (I don't know if you knew that we have an HCI agent for that architecture)

@zmrocze now this repo has a skeleton if you to take a look. Anyway #2 and #3 (which should be implemented in mlabs-haskell/devops) still have the priority.

@zmrocze since perhaps the CI thing it's a big confusing. Currently this repo has a working CI but it's still using the MLabs agent. Instead it has to use an ad hoc agent that pushes to an ad hoc cache.

Closes #1

Edit: hasn't worked automatically :( I'm (manually) closing #1
