Tutorial: OAuth2.0 with ORY Hydra, Vapor 3 and iOS - Part 1: Setup Hydra

Hey IH, over the last couple of weeks we started building a product, that deserves a focus on security, so we figured that we should have a proper authentication/authorization system in place. We used ORY Hydra (https://www.ory.sh) for this, but felt that the documentation focused on people who were already very confident with OAuth2.0 and OpenID Connect. We were a little bit confused on what we would have to build ourselves and what was already provided by Hydra. That's why we wrote a 4-part tutorial, that should help those who might have the same feeling when using Hydra, which is a great product by the way.

So here is Part 1 of the tutorial:

I'm open for questions and feedback :)
