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
