Once WebDAV is back in Zope itself (zopefoundation/Zope#744) all WebDAV-related functionality here can stop depending on or testing for the presence of ZServer.
Furthermore, since FTP will most likely not come back, all FTP-related functionality can be stripped out.
In the end, there should be no dependency on ZServer anymore, which means a whole class of test configurations can go away.
