Make development setup easier

[th0mas]

Currently setting up a development environment is a pain due to there being no clear way to generate auth tokens for the API.

I think(?) theres a function in Auth_plug that can generate Auth tokens client side, we should see if we can add this to a Mix command

• Add a command to generate an Auth token automatically for development

Making development setup easier is a very broad term, here are a few ideas that could help:

• Documentation: We can increase documentation and add some helper commands to make creating and developing auth keys easier but still require manually obtaining and starting the development servers.

• Docker: Try for a 1 click install by running docker-compose up. This can have an added benefit of a controlled development environment but will require a large amount of upfront cost.

• Scripts: Try for a 1 click install using shell/python(?) scripts that will pull and set everything up. These may not always work (e.g. Linux/Mac/Windows) differences but will be a lot lighter to run/less dependencies

@nelsonic thoughts?

@th0mas Yeah, creating Auth API Keys is not going to be easier.
We've got it down to a single environment variable.
(unless you can think of a way to automate it...?)

Please note: the UI for Auth API Key creation is going to change shortly due to the creation of "Apps" dwyl/auth#95
But it will be the same number of steps and single environment variable. I will update the screenshots/steps in my PR.

As for using Docker, unless we are deploying using docker (and don't have any other choice),
I would prefer to avoid it because it's another thing to have to maintain/update.
While we have a precedent for using Docker see: https://github.com/dwyl/learn-docker#docker-and-pete-stack
@SimonLab is using it to run Postgres on his machine: dwyl/learn-docker#15 (comment)
I'd prefer to attempt the (well commented/documented) Python approach if possible,
but it depends on your estimate for how long you think it will take.

Not at all concerned about this working on Windows. In fact I would add "Microsoft Windows Not Supported" to the README.md to avoid any issues from people attempting to run it. We will never use Windows for anything secure. 💔
