[Galene] Installation Script

Hi,

I have implemented and tested a script to install Galene and a TURN that works behind a Router, even a domestic one.

You can doowload it here : https://gitlab.inria.fr/rouillie/visio/-/tree/master/galene

It works only for Ubuntu 20.04 or Debian buster for the moment, mainly because I am lazy :-) but it opens the door to an very easy deployment on a cloud or simply at home.

Cheers,

Fabrice
