Switch from Beeline to OTel

[aarongable]

We currently use honeycomb's beeline-go library for collecting traces. This library is in maintenance mode, as the observability/telemetry industry has converged on the Open Telemetry protocol for collating and exfiltrating traces. We should switch to using the opentelemetry-go library instead.

Alternatively, we should remove our tracing infrastructure entirely until we're ready to actually export our traces.

I've started working on this when I have a bit of time @ #6750
