Merge pull request 'Reorganize dependencies' (#373) from improve-deps into main
This PR includes work from @jirutka : - [x] Allow linking against system-provided libraries (libsodium, libsqlite, libzstd) #370 - [x] Make OTLP exporter optional and allow building without Prometheus exporter (/metrics) #372 And also: - [x] Update `.nix` files - [x] Remove heed default-features - [x] Bump versions of all Garage crates to 0.8.0 - [x] Make db engines (lmdb, sled, sqlite) optionnal - [x] Add documentation for available features - [x] Directly include code of previous versions used for migration in order to reduce dependencies - [x] Read variable `GIT_VERSION` from garage main instead of in crate garage_util to make builds faster - [x] Report features used in the build somewhere? (in `garage --version` or something) - [x] Check we `warn!` correctly if we try to use deactivated feature - [x] Allow not to launch S3 endpoint if not in config Reviewed-on: https://git.deuxfleurs.fr/Deuxfleurs/garage/pulls/373
