    Adds in the experimental test runner
    
    Adds an experimental test runner based on the JUnit Computer interface.
    
    This interface can only run whole classes at a time, so we still use the legacy test runner for Serial tests.

commit defdfaadce7aa4a9e0e75dc62284467a522bd2b7

    Flush out some bugs with the 'parallel methods' running in the legacy runner.
    
    A few bugs were brought to the light after adding -default-concurrency PARALLEL_METHODS around running all tests.
     - Some tests were not properly being ignored and caused extra XML output.
     - The list of sharded tests was not deterministic. This is because the method list returned by Class.getMethods() does not return methods in a deterministic order.
    
    These problems would have only been seen by someone using the experimental PARALLEL_METHODS mode of running the test runner so shouldn't have much impact for existing users.
    
    Fixes:
     - Use the parameterized test runner to run with -default-concurrency PARALLEL_METHODS.
     - Extract TestMethod to a standalone class an34d add tests.
     - Make sure list of TestMethods created in a deterministic order.
     - Make sure that we only consider testable, runnable classes before making requests for each method.
     - Consolidate functions that analyze test classes into the Util class.
     - Add more tests for the Util class.

commit 76c8411a272e741d8541d8ea7593bb8b1f561470

    Parameterize the test runner so it can re-run all tests with paralleism enabled.
    
    This is a bit more infrastructure around testing before landing the experimental test runner.
    - Parameterizes the ConsoleRunnerTestBase so it can re-run all tests with parallelism enabled by default.
    - Moves some tests around, making a separate XMLReport test.
    - Moves some test classes from the impl to the lib package.
    - Remove the -parallel-methods argument. It was marked experimental
    - Prepares for re-running all tests with the experimental test runner on.
