Make the auto ip parameter auto_ip

There was a parameter in the docs called 'public_ip' that didn't
actually exist. Additionally, auto_floating_ip is not consistent with
the underlying parameter which is auto_ip - for no good reason.

Add auto_ip as the real parameter, and then make public_ip and
auto_floating_ip as aliases for it for backwards compatability.

Fixes #2301
