Update Java-jersey2 client to skip binary support

Binary parameter/response support was added to the default Java client
codegen which changed the signature of the `invokeAPI` method in
"api.mustache", causing the "jersey2" client fail to compile.
Here an separate version of `api.mustache` is added for "jersey2" client
which does not handle binary support (for now).
