Set-up vanilla jitsi meet

Due to repeatedly connectivity problems on meet.fairchat.net on heu20, we should set up a new instance somewhere else to be able to compare. The less internal networking and firewalling the better.

Variants:

1. @cw is offering to put it on some new hardware in July 2018, if a well known customer is ordering it
2. @ayers for such test and compare cases we could maybe also use the EDI server
3. rent a used iron at Hetzner for € 25.- - Jitsi Meet just needs 1 GB RAM and not much CPU power
4. rent a VPS at OVH for € 4.- https://www.ovh.de/virtual_server/vps-ssd.xml
