sslutil: drop support for clients of sslutil specifying a TLS version We really just want to support the newest thing possible, so we may as well consolidate that knowledge into this module. Right now this doesn't change any behavior, but a future change will fix the defaults for Python 2.7.9 so we can use slightly better defaults there (which is the only place it's possible at the moment.)
