Add Windows hosts
In MR !28 (merged) I'm adding MSVC CI using Windows docker, but it needs hosting on Windows. There are instructions here to setup the host. Currently I have a spare x230 installed with Windows hyperV server 2016
connected on my account: https://gitlab.freedesktop.org/xclaesse/gst-ci/-/jobs/49419.
On gitlab.gnome.org, Christoph Reiter is paying for 2 Windows VMs on https://www.hetzner.com and that seems to do the job. It seems pretty cheap, we could start with that, we can always migrate to another hosting if needed, that's the power of docker :-)
