ChromeDriver uses the following log levels:

ALL, DEBUG, INFO, WARNING, SEVERE, and OFF

See https://cs.chromium.org/chromium/src/chrome/test/chromedriver/logging.cc

Selenium uses:

"OFF", "SEVERE", "WARNING", "INFO", "CONFIG", "FINE", "FINER", "FINEST", "ALL".

Please add a mapping between the two list like for Firefox here: https://github.com/SeleniumHQ/selenium/blob/master/java/client/src/org/openqa/selenium/firefox/FirefoxDriverLogLevel.java

Chromium is probably also affected.

The same needs to be done for the Python implementation of Selenium.
