[Perf] Fail pipeline if one or more perf tests fails

If one or more perf tests fails, the pipeline should be considered to have failed (turn red), though it should run all tests even if one fails. I believe this can be accomplished by having the `PerfAutomation` app set a flag if any test process returned a non-zero exit code (or returned -1 for throughput). We may also need to update the perf framework in each language to return a non-zero exit code on failures.
