Description

Allow FS declarations to have a config option to provide a URL to include in any diagnostics message if the FS class doesn't load, e.g. {{"ClassNotFoundException: failed to load swift://fs/file -please see http:// something }} for help.

This could be similar to the NetUtil.wrapException() code, only with per FS URLS. We could fall back to a wiki page if there was no URL
