Fixup performance suite test runs.

Add new test suite performance_optional, add less important performance tests
to that suite and schedule it for nightly run.

Add/Remove the tests from the performance suite so it matches the dashboard
exactly.  Scedule these more important tests for every build, this is an
experiment to see if we have enough DUT resource available for such
frequent runs.
