Add 'ignore-trailing-jobs' as optional flag

[emilkovacev]

nb-tester by default uses QiskitRuntimeService to cancel trailing jobs. This assumes that jobs are run using that same configuration, as opposed to being passed in via a patch. For notebooks run with fake backends, this should not be a requirement. The flag '--ignore-trailing-jobs' allows users of nb-tester to skip the step to cancel trailing jobs.

Thanks for contributing to Qiskit documentation!

Before your PR can be merged, it will first need to pass continuous integration tests and be reviewed. Sometimes the review process can be slow, so please be patient. Thanks! 🙌

This seems useful.

I don't think we want ignoring trailing jobs to be the default, though. Most users of nb-tester do want the safer behavior of canceling trailing jobs. It would be surprising to need to specify an arg to do the safe thing. This would be a gotcha for our local users of nb-tester in this repository.

What do you think of renaming --cancel-trailing-jobs to instead be --ignore-trailing-jobs? So, we keep the default behavior the same as the status quo.

Seems reasonable to me! I rewrote the functionality to work as you described.
