Ahodges/video upload

Initial draft of the "Processing Video Files" guide for consortium members describes the procedures needed to get an institution up and running (video_prereqs.rst) and for course teams to upload video files (video_uploads.rst).
An HTML version is available at http://draft-processing-video-files.readthedocs.org/en/latest/
@nasthagiri, @frrrances please review video_uploads.rst in particular.
@lou-wang, @srpearce please review from your knowledge bases. 
@mhoeber, @catong FYI.
Sending HTML link to Greg Martin and Rachel Grubb also. Please tag any other reviewers as appropriate.
Rachel would like to begin sending the HTML link to interested course teams ASAP.
There are two different processes reported by this page: the upload process, which can be in progress, complete, or fail, and the automated transcoding etc. that edX does, which can also be in progress, complete, or fail. There is a title only for the section of the page that lists files undergoing edX processing, and not for files that are uploading. That title gets pushed to one side when you upload a file, rather than appearing below the uploading files, so it is somewhat hard to describe what the two sections look like or where they are in relation to each other.  (Exact status names in UI do not match specs at this time, unsure what they will be at release.) There is a sandbox here:
