This allows for usage of settings variables in templates, e.g
```
{% if settings.USE_ANALYTICS %}

I am getting an error if I create a signal.py file under users model. Here is the stacktrace

Having the signal be imported from project_slug.users.signal fixes the issue.
- Change celery app to not be a Django app, more like a WSGI app
- Define a Celery task in the Django users app
- Write a test to execute the task
- Update scripts to use the new app to start workers
- Update documentation
Fix#865
## Description
Following up on @webyneter attempt in #1205, which is now getting outdated, I've tried to make Gulp task runner work with Docker. There is no documentation yet, but this seems to work locally with the custom bootstrap compilation...
- [x] Add a node image for local developement
- [x] Proxy the django image rather than localhost in Browser sync, pass header to keep hostname
- [x] Don't call the runserver command from Gulp, let docker-compose handle
- [x] Update package.json & gulpfile.js templates to reduce the number of unwanted empty lines
- [x] Use [multi-stage build](https://docs.docker.com/develop/develop-images/multistage-build/) in production to make sure the static assets are produced
- [x] Update documentation
- [x] Verify that the previous issue with static assets missing from production isn't there
## Rationale
Currently, the static build isn't working nicely with Docker, extra manual setup is required.
Fixes#1762
