Concurrent local selenium execution using multiprocessing_on_dill
A local selenium pool for increased testing performance without requiring multiple hosts. multiprocessing-on-dill is used to provide a configurable number of Chrome webdriver instances on which to simultaneously run selenium tests. Each instance reuses its applicationCacheEnabled = False webdriver for multiple tests, erasing all cookies between tests. After the pool of webdrivers has no remaining tests to execute, it creates a JSON report in an XUnit style.
