Explain more specifically how to use flutter drive/what it does (#161450)

Browse Source 
_Run integration tests for the project_ is not an accurate statement, as
there is nothing inherently about `flutter_driver` that is for
integration tests (for example, it could be just plain automation,
benchmarking, etc).

In addition, clarifies what the most common two arguments might be and
their defaults.
