xk6-tracetest

This extension adds Tracetest support to k6!

That means that if you're testing an instrumented system, you can use this extension to trigger test runs.

Currently, it supports HTTP requests and the following propagation formats: tracecontext, baggage, b3 ot, jaeger and xray.

It is implemented using the xk6 extension system.
