Always keep chromedriver running for faster subsequent startups

Browse Source 
Removed the persistent_chrome config flag - chromedriver is now always
kept running after webdriver_quit. This eliminates startup latency for
subsequent WebDriver sessions.

Safaridriver is still killed on quit since it doesn't benefit from
persistence in the same way.

Updated quit message to correctly indicate chromedriver remains running.
