The TracingHandle::flush function allowed a user to pass in their
own (optional) oneshot::Sender<()> to get notified once the flush is
completed, but that's making things unnecessary complicated.
By simply having the flush() function await the flush, we make its
interface more intuitive, and callsites (only inside tvix-tracing itself
so far) simpler.
We can also remove the Option around the oneshot::Sender entirely, as we
now always call it with that.
For some more clarity, we can remove the channel from the struct fields
entirely if otlp support isn't compiled in.

When uploading a Store Path to a Nix HTTP Binary Cache, Nix first does a
HEAD request for $outhash.narinfo, and if that's not found, for
`{narhash}.nar[.compression_suffix]`.
If the NAR is already present, only the NARInfo is uploaded.
Even though we don't have a service allowing to globally look up from
NARHash to root node, `root_nodes` in `AppState` at least contains
recently uploaded NARHashes.
If we find it in there, we can prevent Nix unnecessarily uploading NARs
if the same contents have already been recently uploaded.
We also promote this key, chances are high Nix will subsequently upload
a NARInfo referring to this NARHash.
