Smoother develop/deploy workflow onboarding

[robouden]

DRAFT!!!
I would propose we make an overview (like we have for the infrastructure) for the development setup. Feel free to add, modify.

• integration of different repos
• flow of development
• development to publishing (local->dev->production)
• different ways to deploy
• credentials needed to work (local permissions, slack, GitHub, AWS)
• AWS console ES/Beanstack/S3/LB/instances relation/setup.

Considering this in-progress since my work on #810 ties into this

Once gitpod support is merged and working, we can center the docs around that rather than trying to maintain setup docs for multiple OSes.

I haven't tested it yet, but for deployment I think we can set up gitpod for safecast_deploy and have people add AWS keys to their gitpod account according to the docs on https://www.gitpod.io/docs/environment-variables/

Though it might be more fun to make a slack-bot based deploy system instead and then no-one has to clone safecast_deploy unless they're working directly on the deploy tooling.

Gitpod is all done and merged. Still need doc updates
