_get_server_floating_ip is not returing a float in all cases

In some cases.. depending on the tenant networking _get_server_floating_ip

and returns the floating ip address.

port to the default ipv4 address
"tempest_default_ip": "192.168.40.3"

Somewhat revert I7087701c63906f2a9843a4479947eb4fe8c7fd4e

The tempest_default_ip doesn't need to be a new fact. This was already
in the iptables defaults, but commented out. Uncommented the default,
and changed the task to match the tempest_ip name.

- moving all common methods to functions.bash
- sharing the generate_settings_file function between run and
  generate-settings-file.sh
- making setting.sh into an executable script so that the

      source /path/to/my-khaleesi-settings.rc
     ./generate-settings-file.sh icehouse-multi-rhel7.yml
