title: allow All trafic to and from the instance using boto
body: <p>The following code works as expected.</p>
  
  <pre><code>import boto.ec2
  conn = boto.ec2.connect_to_region("us-east-1", aws_access_key_id='xxx', aws_secret_access_key='zzz')
  
  sg = conn.create_security_group('test_delete', 'description')
  auth = conn.authorize_security_group(sg.name, None, None, ip_protocol='tcp', from_port='22', to_port='22', cidr_ip='0.0.0.0/0')
  </code></pre>
  
  <p>I can select "<strong>All traffic</strong>" option from user interface. There is no equivalent here in boto. 
  I am aware of the security risks involved, but for some reason I want to open all ports (to / from) for all traffic using boto.</p>
