Enables tracing panic hook in addition to pageserver introduced in
#3475:
- proxy
- safekeeper
- storage_broker
For proxy, a drop guard which resets the original std panic hook was
added on the first commit. Other binaries don't need it so they never
reset anything by `disarm`ing the drop guard.
The aim of the change is to make sure all panics a) have span
information b) are logged similar to other messages, not interleaved
with other messages as happens right now. Interleaving happens right now
because std prints panics to stderr, and other logging happens in
stdout. If this was handled gracefully by some utility, the log message
splitter would treat panics as belonging to the previous message because
it expects a message to start with a timestamp.

## 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)

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.
