Integration test improvements (#447)

A few improvements to the integration test:

* Search for test files recursively in the test dir
* Output a test report at the end for a quick summary of what tests passed/failed/were skipped
* Add support skipping test files; skip the logging test since it's broken (#446 is tracking this)
* Switch to latest helm version
* Cleanup namespace
