Subject: [PATCH] Allow users to set the test run concurrency

It will default to 0, which means testr will automatically set it based
on your CPU count. Allowing the user to set it with an environment
variable lets them control the resources used and more easily debug any
issues with tests impacting each other (by disabling concurrency).
