Description
When using the selenium grid, not defining the binary version on nodes that have multiple versions of browsers can lead to errors.
The solution proposed is to extend the DesiredCapabilities capabilities provided in the "remote" case of $NUTCH_HOME/src/plugin/lib-selenium/src/java/org/apache/nutch/protocol/selenium/HttpWebClient.java provided in NUTCH-2083 to explicitly indicate the browser path.
