fc-agent: add structured logging output for better error reporting and more
insights into what automated updates are doing. This also changes the output
of the fc-manage command when run manually to give better user feedback.
Structured logging output can be explored with journalctl or graylog (loghost)
(#PL-130029).
Jitsi: fix Jibri recordings (#PL-130037).
We continued porting Ceph to NixOS: we have now included the RadosGW and fixed
multiple bugs (#PL-127635).
