Refactor FIP extraction

"openstack server list" produces different output for different OSP
versions.

This change gets the very last IP from "openstack server list" which
will be the last IP of last active network and uses it for finding
correspondent Floating IP. Regexp extract IPv4 or IPv6 IP allowing to
have diffent formats of output.
