Partial generation of jbossws-cxf.xml descriptor

See http://community.jboss.org/message/640779#640779 . Basically the issue with the need for user to specify every endpoint in the jbossws-cxf.xml, while in some case the info might come from the metadata created from the web.xml / annotations. At least we could have defaults.
The same applies to defaults for the address attribute in jaxws:endpoint.
