Upgrades Hydra to the latest master/flake branch. To perform this upgrade, it's needed to do a non-trivial db-migration which provides a massive performance-improvement[1]. The basic ideas behind multi-step upgrades of services between NixOS versions have been gathered already[2]. For further context it's recommended to read this first. Basically, the following steps are needed: * Upgrade to a non-breaking version of Hydra with the db-changes (columns are still nullable here). If `system.stateVersion` is set to something older than 20.03, the package will be selected automatically, otherwise `pkgs.hydra-migration` needs to be used. * Run `hydra-backfill-ids` on the server. * Deploy either `pkgs.hydra-unstable` (for Hydra master) or `pkgs.hydra-flakes` (for flakes-support) to activate the optimization. The steps are also documented in the release-notes and in the module using `warnings`. `pkgs.hydra` has been removed as latest Hydra doesn't compile with `pkgs.nixStable` and to ensure a graceful migration using the newly introduced packages. To verify the approach, a simple vm-test has been added which verifies the migration steps.
