This test suite runs automated power tests that should all pass. These
tests are run on every build and thefore each test should be short
and not take more than 5 minutes to run.

This suite runs the test list on systems with AC off (on battery)
since they require use of the rpm.

The tests that run with AC on are run through their normal control
files since they do not need to interact with the RPM.
