Comment 2 for bug 1491461

https://bugs.launchpad.net/fuel/+bug/1488471 < - this was introduced because of https://review.openstack.org/#/c/215270/18/deployment/puppet/osnailyfacter/lib/puppet/parser/functions/generate_vips.rb,cm

Instead of doing p_vipname[0,13], let's do p_vipname[0,8] + short hash of 5 chars for vip to make unique, idempotent interface names so that we can enable longer VIP strings.
