Feature request: Configure JUnit per-run instead of per-repo

[tsheinen]

Motivation

https://nexte.st/docs/machine-readable/junit/ suggests writing a CI profile to enable JUnit in the per-repo configuration. I'm writing a template that should work generically across many rust repos. Currently, I'm telling consumers to just add this to their config. I would prefer to configure this in some method at the cargo nextest run call site so we can generate JUnit reports without modifying the underlying repo.

Proposal

I'd like to allow configuring JUnit by environmental variables or command line switches with similar semantics to configuration options which can already be configured in multiple ways. I'm happy to write an MR to do this :)
