db72812f01 Use the new cargo feature resolver "2"
Garage currently uses the legacy resolver "1". The new one is used
by default if the root package specifies 'edition = 2021', which
Garage does not (yet).

The problem with the legacy resolver is, among others, that features
enabled by dev-dependencies are propagated to normal dependencies.
This affects e.g. hyper - one of the dev-dependencies enables "http2"
feature that adds many extra dependencies. If we build garage without
opentelemetry-otlp (this is enabled in the following commit), there's
no normal dependency enabling "http2" feature.

See https://doc.rust-lang.org/cargo/reference/resolver.html#feature-resolver-version-2

b44d3fc796 Abstract database behind generic interface and implement alternative drivers (#322)
- [x] Design interface
- [x] Implement Sled backend
  - [x] Re-implement the SledCountedTree hack ~~on Sled backend~~ on all backends (i.e. over the abstraction)
- [x] Convert Garage code to use generic interface
- [x] Proof-read converted Garage code
- [ ] Test everything well
- [x] Implement sqlite backend
- [x] Implement LMDB backend
- [ ] (Implement Persy backend?)
- [ ] (Implement other backends? (like RocksDB, ...))
- [x] Implement backend choice in config file and garage server module
- [x] Add CLI for converting between DB formats
- Exploit the new interface to put more things in transactions
  - [x] `.updated()` trigger on Garage tables

Fix #284

**Bugs**

- [x] When exporting sqlite, trees iterate empty??
- [x] LMDB doesn't work

**Known issues for various back-ends**

- Sled:
  - Eats all my RAM and also all my disk space
  - `.len()` has to traverse the whole table
  - Is actually quite slow on some operations
  - And is actually pretty bad code...
- Sqlite:
  - Requires a lock to be taken on all operations. The lock is also taken when iterating on a table with `.iter()`, and the lock isn't released until the iterator is dropped. This means that we must be VERY carefull to not do anything else inside a `.iter()` loop or else we will have a deadlock! Most such cases have been eliminated from the Garage codebase, but there might still be some that remain. If your Garage-over-Sqlite seems to hang/freeze, this is the reason.
  - (adapter uses a bunch of unsafe code)
- Heed (LMDB):
  - Not suited for 32-bit machines as it has to map the whole DB in memory.
  - (adpater uses a tiny bit of unsafe code)

**My recommendation:** avoid 32-bit machines and use LMDB as much as possible.

**Converting databases** is actually quite easy. For example from Sled to LMDB:

```bash
cd src/db
cargo run --features cli --bin convert -- -i path/to/garage/meta/db -a sled -o path/to/garage/meta/db.lmdb -b lmdb
```

Then, just add this to your `config.toml`:

```toml
db_engine = "lmdb"
```

d2814b5c33 TLS works \o/
So, the issues were:
- webpki does not support IP addresses as DNS names in URLs,
  so I hacked the HttpsConnector to always provide a fixed string
  as the DNS name for server certificate validation
- the certificate requied a SAN section which was complicated to build
  but eventually the solution is there in genkeys.sh
