## Describe your changes
Add libmetrics_build_info metrics with commit sha to storage_broken
/metrics, to match behaviour of proxy, pageserver and safekeeper.
1.66 release speeds up compile times for over 10% according to tests.
Also its Clippy finds plenty of old nits in our code:
* useless conversion, `foo as u8` where `foo: u8` and similar, removed
`as u8` and similar
* useless references and dereferenced (that were automatically adjusted
by the compiler), removed various `&` and `*`
* bool -> u8 conversion via `if/else`, changed to `u8::from`
* Map `.iter()` calls where only values were used, changed to
`.values()` instead
Standing out lints:
* `Eq` is missing in our protoc generated structs. Silenced, does not
seem crucial for us.
* `fn default` looks like the one from `Default` trait, so I've
implemented that instead and replaced the `dummy_*` method in tests with
`::default()` invocation
* Clippy detected that
```
if retry_attempt < u32::MAX {
retry_attempt += 1;
}
```
is a saturating add and proposed to replace it.
Sometimes CI build fails with
error: couldn't read storage_broker/src/../proto/storage_broker.rs: No such file or directory (os error 2)
--> storage_broker/src/lib.rs:14:5

The root cause is not clear, but it looks like interference with cachepot. Per
cargo docs, build scripts shouldn't output to anywhere but OUT_DIR; let's follow
this and see if it helps.
Which ought to replace etcd. This patch only adds the binary and adjusts
Dockerfile to include it; subsequent ones will add deploy of helm chart and the
actual replacement.
It is a simple and fast pub-sub message bus. In this patch only safekeeper
message is supported, but others can be easily added.
Compilation now requires protoc to be installed. Installing protobuf-compiler
package is fine for Debian/Ubuntu.
