ChromeDriver fails in docker container, add option for RemoteWebDriver?

[DragonAxe]

When I run j2cl unit tests using the <webdriver>chrome</webdriver> option from within a docker image, the ChromeDriver fails to start with the following error:

[ERROR] Failed to execute goal com.vertispan.j2cl:j2cl-maven-plugin:0.22.0:test (test-js) on project J2clMavenProject: Failed to run tests: session not created: probably user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir

This is most likely a docker image configuration issue on my part, but I found a workaround which involves using a selenium new RemoteWebDriver(URI.create("http://localhost:4444").toURL(), new ChromeOptions()); to connect to a separate docker container running the docker image from here: (https://hub.docker.com/r/selenium/standalone-chrome).

Would you accept a PR to add support for specifying a "RemoteWebDriver" webdriver and "remote webdriver uri" in TestMojo.java? Or do you have ideas on why ChromeDriver is complaining about the user-data-directory?
