(v3) uploading media files to play in a session

[hiroshisuga]

Is your feature request related to a problem? Please describe.
As have been discussed previously (e.g. bigbluebutton/bigbluebutton#8753), temporarily uploading media files (movie or audio) to the server and sharing them with students during a BBB session would be a really demanding feature, especially for some files that you do not want to upload to YouTube by whatever reason.

Describe the solution you'd like
The unprecedented work by @pedrobmarin has not been implemented by security concerns (as far as I understand), but the new version of GreenLight seems to have a more secure architecture to upload media files. It would be nice if we can share the link to media files that the admin uploads to GLv3 server and plays them during a lecture.

Describe alternatives you've considered
I am still using the Pedro's PR on BBB2.4. I may want to try transplant it to BBB2.6...

In 2.6 i think its possible to have links of audio/video in slides, and they appear to be selected in external player.. if you make the text white, or hide them behind a shape the link wont show to students... So your class slides can add the links for you i think. Have not tried, but saw some video clips of it working. the software is reading the slides text that is used for readers.

Hi @hostbbb , yes it's possible to show your own audio/video files that you upload to a cloud server. However there are some cases that I do not want to upload files to any commercial cloud server. Thus I would like to have an easy option to upload them to the same server as BBB is running, and completely delete them after the lecture.
