Show ports without IP in instance table and detail

Previously instance ports without IP address were not shown
because api.neutron.servers_update_addresses() ignored ports
without IP address.

This commit changes servers_update_addresses() to include
a special symbol (None) representing "No IP address"
in "addresses" attribute in "server" object.

"(No IP address)" will be shown for ports without IP addresses now.
