Now that the Gitea org uses Drone 1.0.0 we should update the .drone.yml to align with the new format. The current one works, however due to the dropping of groups it takes longer to run.

I'm thinking we also have separate pipelines for each DB that gets tested, so that the services could be terminated sooner (which would decrease resource usage). If we do this we will probably have to have a build step in each pipeline though (a simple TAGS="sqlite" make build would likely be enough). Pipelines supports the depends_on param.

We also have an ARM server that can run docker builds to be able to publish arm builds of our docker image.
