path_exists was returning an error when certain common IO errors were
encountered. e.g. in the path "/dev/null/.", path_exists would throw
an error because the underlying call to Path::try_exists threw an
error because null isn't a directory. But if null isn't a directory,
then the path is invalid, so this should really be returning
false. That's what nix's behavior is and that's what makes sense.
The trait function isn't being changed because some other
implementers (e.g. tvix_store_io) have actual errors they can throw.

When retrieving a closure with get_recursive, the following could happen in the GRPC client:
- The first reference to the deduplicated directory is added to expected_directory_digests
- The deduplicated directory is obtained removed from expected_directory_digests
- The second reference to the deduplicated directory is added to expected_directory_digests
- The deduplicated directory has already been sent, but is still in the
expected_directory_digests. It looks to the GRPC client like the
closure is incomplete and the stream ended prematurely.

This ingests NAR files into the {Blob,Directory}Service, which are
already part of the AppState.
As we then need to correlate the root node to the uploaded PathInfo, we
need to keep a (short-lived) lookup table from NARHash to root node
around. We insert it into a `LruCache` after the NAR is uploaded, and
use `peek()` to do the lookup, which doesn't update the LRU list.

This adds an implementation of nar-bridge in Rust.
Currently, only the GET parts are implemented.
Contrary to the Go variant, this doesn't try to keep a mapping from nar
hashes to root node in memory, it simply encodes the root node itself
(stripped by its basename) into the URL.
This pulls in a more recent version of axum than what we use in
tonic, causing two versions of http and hyper, however dealing with
`Body::from_stream` in axum 0.6 is much more annoying, and
https://github.com/hyperium/tonic/pull/1740 suggests this will be fixed
soon.
