[Floating IP] Neutron support for "ip floating create" command

This patch adds --subnet, --port, --floating-ip-address
and --fixed-ip-address options only. Project related options
will be added in another patch because it relates to identity
v2 and v3, which will make the unit tests too complicated in
one single patch.
