Liviu Rau 9733dacc5c [test] Refactor testrunner (3)
- removed some 'feature envy' instances:
  - created a AugmentedOptions class to take care of non trivial option look-ups
  - moved some calculation closer the the actual data
- promoted parameter that was passed around a lot (options) to filed in the offending class
- similar object creation looks a bit more similar
- CommandContext provides a wrapper that ensures resource de-allocation
- separate tests from standard and num_fuzz runners
- added a couple of more tests to improve coverage

This is still in flux. But further changes risk creating a disconnect between the original implementation and further refactorings.
