adds automated SOAP tests

This adds simple SOAP servers using Apache CXF
Using JSR 181, we can annotate pojo into several flavors of SOAP
servers (except RPC + encoded). This has caught several bugs.
- Apache CXF sometimes encodes string with minOccurs = 0. scalaxb
wasn’t using Option[String].
- scalaxb was only generating defaultScope for targetNamespace from
xsds. It now adds targetNamespaces from wsdl.
