         - host - IP address for the service
         - log_level - log level you would like the service to run.

         - options - IE Options instance, providing additional IE options
         - ie_options - Deprecated argument for options
         - desired_capabilities - alias of capabilities; this will make the signature consistent with RemoteWebDriver.
