Context conflict with xk6-browser

[pablochacin]

When running an script that injects faults using the disruptor using a custom build that includes also the xk6-browser extension, the following error is reported.

ERRO[0000] GoError: error creating ServiceDisruptor: error creating ServiceDisruptor: client rate limiter Wait returned an error: context canceled

This happens even if the script does not use the browser extension (e.g. this demo script)

Running a script with this custom build (k6 + xk6-disruptor+ xk6-browser) that use the browser but not the disruptor works as expected.

This context can be traced back to:

	k8s, err := kubernetes.New(vu.Context())

So it is in principle the VU's context.

The disruptor does not return until the fault injection ends. Therefore it is unlikely that this VU ends while the fault injection is running.

[pablochacin]

The cause of this behavior is a change in the way the context is managed in k6. This change appears in the k6 v0.41.1 which is a requirement for xk6-browser. If the binary is compiled without xk6-browser the version used is v0.41.0.
