Move Go files into src directory

[AlexisDeschamps]

Issue: #16

Testing

See that the output is as expected for:
Run make dev
Run make test

@jakehobbs It loos like this works out of the box. Do you know if there is an expected way it could break?

The dev Dockerfile also needs to be updated with new path: go build -o alc-mobile-api ./src, then I think this should be fine.

I think the problem I was running into before was just that I was also trying to move the templates, static, and model directories into src. But maybe that is not something we want to do.

@jakehobbs Cool, thanks. I tried to also do that and made some other updates Does Dockerfile-prod not also need to be changed?

Tests I ran:

• make dev: output looked the same as the main branch
• make test: output looked the same as the main branch
• docker build -f Dockerfile -t dev-test .: output is stderr: 2021/09/13 00:26:13 missing configuration for DB_DSN so it seems to work
• docker build -f Dockerfile-prod -t prod-test .: output is stderr: 2021/09/13 00:26:13 missing configuration for DB_DSN so it seems to work

Everything seems to be working for me locally with a full config. Do we want the model directory to be inside of the main directory though? It feels a bit weird to me, but I'm not sure what the standard practice is.
