installer: homebrew recipe for macOS users

[phrohdoh]

homebrew is the defacto package manager for macOS.

The name hydra is already taken as a recipe name so perhaps hydra-oauth2 could be used.

This would make installation and upgrading much simpler for end-users.

I would prefer ory-hydra as a name. However, I have little experience with homebrew. If you want and know how to write homebrew recipes I'd love to see that! If so, ping me on Gitter :)

While this would be nice to have, we do not have the resources to support this. Maybe later we will be able to provide different installation options using homebrew, aptitude, chocolate, ...
