Rerun test with a new label

[Nooshu]

Feature Request Summary

Maybe add a single "New Test Label" input field next to the "Re-run the test" button, allowing a test to run with the exact same setup parameters only with a new label.

What's the motivation or use case for the change/feature?

Many times I've wanted to rerun a test, say a day or so after making a production change, only to have to try to remember all the parameters I used in the test, with only the label changed to "[test run name] - x fixed". The ability for WPT to remember the setup parameters with only a new label would save so much time.
