Add blazor scenario

[ooooolivia]

Adding blazor scenario for blazor sod:
$(Python) pre.py publish --- set up by creating a blazorwasm template and publishing it
$(Python) test.py sod --scenario-name <scenario name> --- run the test for its size on disk

Everything LGTM, but I have one quick question. How do the arguments passed to test.py get routed into the runner?

[ooooolivia]

@DrewScoggins Do you mean sod and --scenario-name? The ArgumentParser is created in runner.py and we just parse when we call Runner(traits).run()

performance/src/scenarios/shared/runner.py

Line 98 in ecd9653

self.parseargs()
