Feature Proposal: Where possible, make auto-rerun tests run on a different machine

[adamfarley]

Summary Proposal for the auto-rerun test feature to mandate (where possible) that the reruns happen on a different host.

Details If a specific unit test failure is caused by something specific to a particular host, this change allows us to avoid that problem.

Statistics Summary Tests which failed and reran on the same host: 84 ...of which this many failed: 78 Tests which failed and reran on a different host: 173 ...of which this many failed: 124
