Subject: [PATCH] Add SystemInformation test

The SystemInformation test always passes. It prints out the contents of
various configuration parameters. The intention is to capture this
information in dashboard reports. That way if a change causes a
dashboard failure and a developer does not have access to the dashboard,
she can look at the output of this test to see the configuration of the
build and that machine.
