Expose a RerunRequest exception and a rerun_if(condition, reason) helper that discards the current attempt and retries while the test still has reruns left. Combined with only_rerun=[RerunRequest], tests can restrict reruns to exactly the known-bad generated-data case instead of any failure. Closes pytest-dev#58.
