title: How to change CQL version?
body: <p>When i try to connect to cqlsh I get this error:</p>
  
  <pre><code>Connection error: ('Unable to connect to any servers', {'127.0.0.1': ProtocolError("cql_version '3.3.1' is not supported by remote (w/ native protocol). Supported versions: [u'3.4.4']",)})
  </code></pre>
  
  <p>If I add explicitly version like this <code>cqlsh --cqlversion=3.4.4</code> it is fine, but I wonder how to set CQL version to be 3.4.4 by default so I can connect without parameter ?</p>
