Patrick Ohly 550d4c0074 scheduler_perf: support test case selection via labels
Entire test cases and workloads can have labels attached to them. The union of
these must match the label filter which works as in GitHub. The benchmark by
default runs the tests that are labeled "performance", which is the same as
before.
