This commit contains: - FlutterDriver API for e2e tests usable in conjunction with package:test - FlutterDriverExtension to be enabled by the application in order to allow an external agent to connect to it and drive user interactions and probe into the element tree - initial implementations of tap, findByValueKey and getText commands (to be expanded in future PRs)
