feat: Set up project scaffolding with Docker Compose, Gin webserver, and Redis

[alexluong]

Development Setup

$ git clone ... & cd EventKit
$ cp .env.example .env
$ docker compose up

This should work. I already set up live reload with Docker too so when you make changes to the server, it should be reflected during development.

Let me know if you'd like to make the server work without Docker Compose. I think we may need to add some code to read environment variables and that's about it.

Business logic directories

Besides the boilerplate setup code, the meat of the project should probably be in the business logic packages like destination, tenant, event, etc. Currently, I have things pretty flat, everything is inside internal and that's it. If you think it makes sense, I can try to organize the packages a bit so there's a better differentiation between glue code and business logic.

CRUD ops

Please check out destination/handlers.go to see the CRUD operations. I think one potential missing thing is how we want to treat errors. I don't see that in the design document yet, so I'm just returning the status code for now. If we have a certain error format, we can potentially write a helper to transform Go err into that structure.

Postman

Here's the Postman Collections I have for this so far, just in case it helps.
