This PR introduces some backend python + REST APIs for storing static
asset files along with an XBlock in a content library. It also updates
the new runtime to be able to load such static asset files.
Example use cases:
* Store an image file with an HTML block and then use the image inline
in the HTML block.
* Store a PDF file with an HTML block and provide a link in the HTML for
the learner to download the PDF.
* Store .srt files or even video .mp4 files that belong to a video
XBlock.
Within the bundle, these static asset files are stored in a "static/"
subfolder of the folder that contains the OLX file. Extending an
existing LMS/Studio convention, a static asset file such as "image.png"
is referenced within the OLX as "/static/image.png" and the URL will be
rewritten by the runtime.
Using six.text_type() is converting
MarkSafe object created using HTML
function to simple string which is
essential html tags interpolation.
Applying escaping via Text function on
this string object is causing escaping
of html tags.

Some of the email templates are escaped
in such a way that could potentially cause
double escaping i.e via django default behaviour
and other via interpolate_html tag. Fixing it
by only applying escape via tag.
