    Enable offline compression for resource files

    The default value for OFFLINE_COMPRESS is False, as per the Django
    compressor docs. When using offline compression, it seems that different
    request contexts may generate different CSS files with different names
    by way of the SCSS generator. When the HTML is returned to the browser,
    the CSS filename referenced will only exist on the node that received
    the initial request and generated the CSS file locally, however in a
    load-balanced scenario with multiple Horizon instances, the actual HTTP
    request for the CSS file has a n-1/n chance of hitting another node that
    may be lacking that file, resulting in an unstyled page.

    Changing the OFFLINE_COMPRESS value to True enables Django to use the
    pre-generated list of resources -- created via the manage.py compress
    command -- which is stored in a manifest.json file and should be the
    same name/content across the instances since it's not varying by request
    context like during online compression.
