Previously, we set up headscale
We need to enable tailscale on baxter, as we intend to use tailscale to
connect builders to its buildbot instance
As the headscale server doesn't automatically put the server running it
into the tailscale network, we also need to set up the tailscale daemon
on axol
For a while we've been lacking a CI, which has led to problems such as
an inability to enforce REUSE, as well as an inability to build and
deploy docs-site automatically
Buildbot is commonly used (nix-community, lix, etc.), and very
extensible, which we hope will benefit us over something like Hydra or
Typhon
The buildbot instance is available at https://builds.auxolotl.org
