Disable SSLv3 Ice protocol for all languages

To mitigate the POODLE/SSLv3 vulnerability, all Ice
languages are being restricted to TLS protocols. Here, we've
chosen `tls1` as the protocol setting in order to support
Ice 3.4 and Ice 3.5 at the same time. In practice, a newer
version of the TLS protocol will used if available.
