Change default security group protocol to 'any'

The default protocol used to create a security rule was changed to
``tcp``, which was a regression from the neutron client.  Change it
back to ``any``, which skips sending the protocol to the API
server entirely when using the Neutron v2 API.

Users that had been creating rules without specifying a protocol
and expecting ``tcp`` need to change to use ``--protocol tcp``
explicitly.
