The deploytime connectivity (ping) tests are failing in an ipv6 based deploy

[Marios Andreou]

As part of deploy we use ping to determine network connectivity is ok so that we can fail early, like at https://github.com/openstack/tripleo-heat-templates/blob/d148ddbe785696e2eb5238c07fba52089ff00ef2/validation-scripts/all-nodes.sh

When testing a deploy using the ipv6 templates, from https://review.openstack.org/#/c/235423/ the ping fails with the IPv6 addresses - specifically ipcalc (which is used to determine if an IP address is included in a given network) fails like:

ipcalc: unable to show setting for IPv6

Initial proposal for fixup incoming

commit 45be848991eb2da0ed039dcaa457800b8ed3f314
Author: marios <email address hidden>
Date: Fri Jan 15 14:00:33 2016 +0200

    Adds v6 capability to the deploy validation test (pings)

    This changes the ping_controller_ips function in the all-nodes.sh
    bash validation script which is run during deployment to check
    network connectivity (to fail early).

    The main differences are using the v6 routes when it is a v6 address
    and using python -c to check if the v6 address is in the network and
    (thanks emachi!) using ping6 instead of ping.
