Don't show an empty spinner for daemon commands.
Move the bar to the right, so the text is better aligned between spinner
progress and bar progress styles.
Generally, push progress bars a bit more down to the place where we can
track progress. This includes adding one in the upload_blob span.
Introduce another progress style template for transfers, which
interprets the counter as bytes (not just a plain integer), and also a data rate.
Use it for here and in the fetching code, and also make the progress bar
itself a bit less wide.

Both umounts happening from another process, as well as tvix-store
itself calling umount() on FuseDaemon will cause the FUSE worker threads
to terminate.
So far there was no nice way to wait on these threads to be terminated
from multiple places, causing the `tvix-store mount` command to only be
terminated if interrupted via ctrl-c, not via an external umount.
Update FuseDaemon to use a ThreadPool, which gives us a join primitive
over all threads, that can also be called from multiple places.
Await on a join() from there to end the program, not the ctrl-c signal
handler as it was before.
Using FuseDaemon from multiple tasks requires Arc<>-ing both the
ThreadPool as well as the inner FuseSession (which also needs to be
inside a Mutex if we want to unmount), but now we can clone FuseDaemon
around and use it in two places. We could probably also have used an
Option and drop the FuseSession after the first umount, but this looks
cleaner.

ClosureValidator was previously only suitable for a very narrow use case:
Validating incoming uploads, which are in leaves-to-root order.
This is because the ordering validation was hard-wired into the add()
function.
This
- Re-name ClosureValidator to DirectoryGraph, which is more suitable
since it actually stores the Directory structs and is drained in the end.
- Move the ordering-related logic to a separate OrderValidator, which
can be used independently.
- re-write DirectoryGraph to be a general purpose
validator which can accept the input in both orders
and can be drained in both orders as well.
This means the DirectoryGraph and OrderValidator can now serve
multiple new purposes:
- Validating the incoming closure on the client while downloading.
- Validating the incoming closure downloaded in a caching layer from the
`far` cache, and re-order it for insertion into the `near` cache.

The problem is that opentelemetry_otlp tonic batch exporter tries to
exports if either the `scheduled_delay` or if the
`max_export_batch_size` is reached. Per default the
`max_export_batch_size` is set to 512 spans, which means that we try to
export these spans once that counter is reached. Each export will then
try to connect to the exporter (if that not already happening) and will
result in a `tcp connect error`.
Increasing the max_export_batch_size to 4096 will then ensure that the
export only happens if the `scheduled_delay` is met after the 10
seconds.
`max_queue_size` is also increased, because `max_export_batch_size`
should not be greater than `max_queue_size`, so similar to the default
config its set to `max_export_batch_size * 4`.
This will reduce the amount of tries to otlp if the collector is not
available and otlp enabled.

This changes that behaviour, applying EnvFilter to all exports, leading

Provide a new interface for forcing a flush of otlp traces and use this
interface to shutdown otlp prior to exiting tvix-store, either if the
tool was stopped with a SIGTERM or ended regularly.
This also fixes an issue where traces were not even exported if for
example we just imported 10 paths and never even emitted more than 256
traces. The implementation uses a mpsc channel so a flush can be done
without having to wait for it to complete. If you want to wait for a
flush to complete you can provide a oneshot channel which will receive a
message once flushing is complete.
Because of a otlp bug `force_flush` as well as
`shutdown_tracer_provider` need to be executed using `spawn_blocking`
otherwise the function will deadlock. See
