Feature request: Re-run the tests

[oriongonza]

Motivation

I'd like to leave my tests running all nights to spot possible race conditions.
Right now I leave it running with "while cargo nextest run; do :; done".

That is not ideal for the following reasons:

1. It doesn't use the CPU at 100%, especially when there are fewer tests to run.
2. If it fails, it stops. Ideally it would log the errored tests to a file and keep running.

Proposal

And endless stream of tests that only finishes when ctrl+cing it

Alternatives

Thanks! Would this be something that would be part of #2219? I think there's a bunch of different stress test modes that can be added.
