[WAGON-618] Remove HTTP file listing with JSoup

[michael-o]

https://issues.apache.org/jira/browse/WAGON-618

[hboutemy]

short question: what is the user-visible effect?

longer form: I suppose no user knows that JSoup is used somewhere to list the content of a remote HTTP directory. Until now, it was magically working, sometimes...
Now that the API will always not work (consistently), is there a user visible output? something like a warning ("listing files on HTTP server xxx is not supported"), or an exception?

And basic question: does it only affect the getFileList(String) Wagon API for HTTP providers? https://maven.apache.org/wagon/wagon-provider-api/apidocs/org/apache/maven/wagon/Wagon.html#getFileList-java.lang.String-

Exception on a call.

Yes, UnsupportedOperationException will be thrown with an appropriate message.

Yes, only. HTTP. Everything else continues to work.
