Extend tracer option testing to all options used by RTLA; test both RTLA setting the default option by pre-setting the tracer to a different value and user-requested value. The tests are done using a script that reads the tracer values inside an --on-threshold action, like existing tests for runtime behavior already do. check_with_osnoise_option is modified to support grep filters, so that it can be used together with the script pattern.
