Authenticator in RequestContext

[lundefugl]

We have connections with kerberos authentication.
At the moment it only works if you set an Authenticator globally.
This is not nice, because there are other connections in the system.

We would like to pass the Authenticator via BindingProvider.getRequestContext().put(...) so that it can be set in com.sun.xml.ws.transport.http.client.HttpClientTransport#createHttpConnection with the call httpConnection.setAuthenticator(authenticator);.
