#strategize(all_tests, run_these_together_groups, thread_unsafe_test_groups, config) ⇒ Object

Combine all discovered test methods with any methods grouped by run_these_together!

Priorities:

- Map over tests to build out groups in order to retain shuffle order
  (group will run in position of first test in the group)
- If a test is in multiple groups, only run it once
