Non-Parallel Testing Events

[fuel-wlightning]

I noticed we have events for Parallel testing. I propose that we add events for normal unit testing.

The Parallel Testing events I think that translate:

• Testing::setUpProcess(function ($token) - Should trigger prior to setup.
• Testing::setUpTestCase(function ($token, $testCase) - Should trigger prior to test case setup
• Testing::tearDownTestCase(function ($token, $testCase) - Should trigger after test case finish
• Testing::tearDownProcess(function ($token) - Should trigger on test finish.

These events would trigger on both Parallel and Non-Parallel Testing, token argument would be null (or maybe false for consistency with ParallelTesting::token()) if not parallel testing.

This could be used for environment setup that is used both for parallel testing as well as non-parallel testing.
