Move videos from the User Manual to a CDN or YouTube

[stevepiercy]

During our recording for World Plone Day, we realized that the videos in the repo contribute about 8MB of disk usage to download. It's not bad now, but as we develop a user manual, this will get in the way of development.

We need to come up with a way to store these videos and screenshots in a CDN, and refer to them remotely, to keep the clone size down. Volto itself with its monorepo structure currently has 46.6MB of disk usage.

If you have any brilliant ideas or suggestions, please add your comment.

+1 but note that at this point we have to rewrite the repository history to remove the commits that include these videos: https://www.deployhq.com/git/faqs/removing-large-files-from-git-history
