SslV2Hello is not supported in https connector

When using an https connector is not possible to choose SslV2Hello (disabled by default in java 1.7). This service override sample show up how to add this support to an https connector, but should be nice to have a parameter on https
to choose wich protocol enable disable (ssl,tls, sslV2HEllo,...)
This is important to connecto to some ws (such as legacyTibco) that accept only sslv2hello

Here there are patched classes
