RFR: 8033113: wsimport fails on WSDL:header parameter name customization

[Miroslav Kos]

Hi,
I'd like to ask for approval and sponsoring fix for following issue (escalation from customer):

   JBS: https://bugs.openjdk.java.net/browse/JDK-8033113
BugDB: https://bug.oraclecorp.com/pls/bug/webbug_print.show?c_rptno=17348912

jaxws changeset: http://cr.openjdk.java.net/~mkos/8033113/jaxws.01/
   jdk reg tests: http://cr.openjdk.java.net/~mkos/8033113/jdk.01/

This fix addresses situation when there are conflicting parameter names 
(wsimport fails) and those need to be customized.

Thanks
Miran
