Right now all blob uploads are performed synchronously, this means if a
NAR contains many small files, the import time is dominated by round
trip time to the blob service. For small files, we can buffer them in
memory and upload them asynchronously to the blob service. Before
returning we make sure to join all the uploads to make sure they
complete successfully before responding OK.
This reduces time to import a bash-interactive closure on my machine
from 1m19s to 7s.

Sets up OpenTelemetry integration for nar-bridge. Right now it will
export spans for HTTP server requests and all gRPC client requests.
Having the spans available will make performance work significantly
easier as it provides a high level overview of where time is being
spent.
In the future we can add application-specifc metrics and
integrate logrus.

This removes the Export method in nar-bridge, and updates all users to
the version now in storev1pb.
It moves the roundtrip test to the importer crate, and some of the
utility functions into a separate util_test.go file.

This adds an additional nar-bridge-pathinfo command.
It exposes a PathInfoService for a HTTP Binary Cache, ingesting data
into a BlobService/DirectoryService as it goes through the NAR file.
It does this whenever it receives a Get request for a specific output
path, and waits returning with the PathInfo response until it ingested
the data.
It does not do any sort of caching - this means it re-downloads NAR
files again whenever the PathInfo is requested again, so you most likely
do not want to use this currently.
It's one building component as soon as we have store composition (which
we currently don't, so don't use this).
It can be used as an alternative mechanism to ingest data (Blobs and
Directories) of a given store path from a binary cache into tvix-store.

This provides a Nix HTTP Binary Cache interface in front of a tvix-store
that's reachable via gRPC.
TODOs:
- remove import command, move serve up to toplevel. We have nix-copy-
closure and tvix-store commands.
- loop into CI. We should be able to fetch the protos as a third-party
dependency.
- Check if we can test nar-bridge slightly easier in an integration
test.
- Ensure we support connecting to unix sockets and grpc+http at least,
using the same syntax as tvix-store.
- Don't buffer the entire blob when rendering NAR
