[libvirt] Time to drop support for Debian 8 (Jessie)?

We currently support Debian 8 (oldstable) along with Debian 9 (stable), but not without some compromises: * the libvirt-dbus, libvirt-ocaml and virt-manager projects do not support the platform at all because it ships outdated versions of some core components; * on the CI side of things, we are forced to drag in the JRE from backports in order to be able to run the Jenkins agent. All things considered, the situation has been fairly manageable up until now, but a couple of recent developments got me thinking that perhaps it's time to let Jessie go: * the distribution has been moved from the regular Debian infrastructure to archive.debian.org[1], a change which has resulted in the daily update run failing and would require investing time to adapt to; * Debian testing has recently entered the full freeze[2], which means the release of Debian 10 can hopefully be expected to happen within the next few month; * even if the Buster freeze period turned out to be exceedingly long, according to our platform support policy[3] we only promise to support a release for the two years after the most recent major release: given that Debian 9 was released in June 2017[4], we would be able to drop Debian 8 support in three months' time regardless of whether or not Debian 10 has been released in the meantime. Based on the above, I suggest we don't invest any time trying to keep Debian 8 chugging along only to drop it in June, and instead declare it as unsupported right now and move on with our lives.
