Refactor testing harness to use defaults (#808)

* Refactor testing harness to use defaults

- Move tests into defaultly named test folders
- Use default test suffix of ".test" instead of "_test"
- Make cluster-store tests unit tests by adding more
    nesting, so that order of tests doesn't matter
