e2e-test setup: gebish, cucumber, and webdrivermanager

I use e2e tests which contain several hundred scenarios, and there are technical requirements for the test cases that I need a “fresh” browser.

For this scenario I use CachingDriverFactory.clearCacheAndQuitDriver()

And there is obviously a different behavior in geb 8.0.0.

I did a random sample with a few selected tests and checked after each scenario how many processes there were for the WebDriver and the browser.
Therfore i use

ps -A -o pid,rss,comm | grep -i 'Google Chrome' | grep -v grep for the browser processes

and

ps -A -o pid,rss,comm | grep -i './cache/selenium' | grep -v grep for the WebDriver processes

With geb 7: everything runs as expected and after each browser restart there is only one browser and WebDriver process.
With geb 8: every created browser and driver process is still remaing also after calling CachingDriverFactory.clearCacheAndQuitDriver() which forces the ci-jobs to terminate in cause of a memory issue
