_get_server_floating_ip is not returing a float in all cases

In some cases.. depending on the tenant networking _get_server_floating_ip
was not returning the float. This change properly goes through all networks
and returns the floating ip address.

networks in the openstack host env can vary open default ansible_ipv4 for tempest

Noticed in some env default and private are the same address.
Ensure tempest can connect to the controller by openging the
port to the default ipv4 address
"tempest_default_ip": "192.168.40.3"
"tempest_private_ip": "192.168.40.3"
"hostvars[tempest_name].ansible_default_ipv4.address": "192.168.50.3"

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.

Run all tasks on localhost without sudo

Playbooks are written to be run with '-s' or --sudo set so that
most tasks need not specify sudo: yes. This inadvertently forces
sudo (nopasswd) to  on development machine/localhost (making it
insecure) unless tasks run on localhost explicitly sets
  sudo: no

Refactor and simplify bash scripts

Simplifies run.sh by
- 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
  following works
      source /path/to/my-khaleesi-settings.rc
     ./generate-settings-file.sh icehouse-multi-rhel7.yml
