title: INSERT a SET<String> into cassandra by passing through a variable
body: <pre><code>INSERT INTO devices (id,dataformat,device_type_id,protocol_id,tags) VALUES ('asd','asdas','sad','asdas',{'asd','as'});
  </code></pre>
  
  <p>This one works perfectly while passing the SET in the CQL but while passing the SET using the code below it shows </p>
  
  <pre><code>Invalid value Set(asd, assd) of type unknown to the query builder
  </code></pre>
  
  <p>Code that i used,</p>
  
  <pre><code>val statement: Statement = (QueryBuilder.insertInto("devices")).value("id",model.deviceId)
      .value("device_type_id",model.deviceType).value("protocol_id",model.protocol)
      .value("dataformat",model.dataFormat).value("tags",model.tag)
  client.executeQuery(statement)
  client.close()
  </code></pre>
  
  <p>The model is of </p>
  
  <pre><code>case class AddDeviceRequestModel(deviceId: String, deviceType: String, protocol: String,
                               dataFormat: String, tag: Set[String])
  </code></pre>
