Fix check_floating_ip_status utility's output

floating_ip variable contains an old state of the floating ip - the state
which was correct before calling refresh method. In order to have the
latest floating ip data after calling refresh, the patch creates a class
as a wrapper around the refreshing ip's state and logging it.
