Remove azservicebus ApplicationInsights-Go requirement

[chlowell]

After #23231, Component Governance still flags azservicebus for requiring yaml.v2@v2.2.1, apparently because that version still appears in go mod graph output. The lowest-effort solution that comes to my mind is moving the stress package into a separate module under testdata, like this.

Hm. I don't think moving it under testdata would be right because I want the project to be built along with the module it's testing.

I can think of a couple of other solutions:

• Update a fork of appinsights, and then use the fork's commit in the stress project (commits from forks are accessible from the main project)
• Migrate over to the OpenTelemetry exporter, which probably has the same issue, but isn't hosted in our repo. I've been wanting to do this one for awhile (based on @lmolkova's enthusiasm) so this might be the better long-term solution.

Migrate over to the OpenTelemetry exporter

I'm very excited about it :) Also would be very surprised if exporter needed yaml.

Looking at the repo I think this might be a case of an indirect dependency of a dependency of a dependency, which might explain why we can't override it like we've tried (maybe). I'm investigating now to see if I can do a cheap fix, then a better one later.

This has been done. We can bring telemetry back using the opentelemetry exporter.
