If `COLLECTFAST_STRATEGY` is not provided in `settings`, `collectfast` has to guess a "strategy". For the case with AWS, it guesses `BotoStrategy` in stead of `S3Boto3Storage`, which is a wrong decision as we `pip install django-storages[boto3]` (`boto3` in favor of `boto`).
Setting `COLLECTFAST_STRATEGY` is also encouraged as `collectfast` is not going to guess the strategy in the future.

This allows for usage of settings variables in templates, e.g
```
{% if settings.USE_ANALYTICS %}
<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id={{ settings.GOOGLE_TAG_MANAGER_ID }}" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->
{% endif %}

I could be wrong about this, but it seems like setting the template
DEBUG setting is redundant, since it should follow whatever the DEBUG
variable is set to.
The settings which are normally prefixed `CELERYD_` are for worker-related config, but since we instantiate the Celery app with a namespace, the prefix for these config should actually be `CELERY_`.
- 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
