Bin/Node: Add an OpenTelemetry trace

What

Add an Opentelemetry trace for receiving/publishing shards.

Why

Ensure the system works as expected.

How

The traceid is determined by the slotid so that it can be shared with multiple names.

Manually testing the MR

Using !15820 (merged) and !15800 (merged), one can do:

dune exec tezt/tests/main.exe cloud dal --proxy -v --log-file /tmp/log --tezt-cloud "gnet-prod" --producers 1 --network ghostnet --memtrace --monitoring --otel --observer-pkh tz3ZmB8oWUmi8YZXgeRpgAcPnEMD8VgUa4Ve --dockerfile-alias debian --fundraiser <fundraiser_key> --bootstrap

And you should observe something on http://gnet-prod.nl-dal.saroupille.com:16686.
