Description of problem:
Some advanced customization steps are no longer valid in RHOSP12 using hieradata because of the way puppet manifests are applied to containers by setting FACTER_uuid=docker instead of the instance UUID as before.

Namely through '/var/lib/docker-puppet/docker-puppet.sh', which is executing puppet like this, 

$ > FACTER_hostname=$HOSTNAME FACTER_uuid=docker /usr/bin/puppet apply         --detailed-exitcodes --color=false --logdest syslog --logdest console $TAGS /etc/config.pp

This will obviously make all hiera-customization to containerized-services based on the servers UUID to fail. According to this article, https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/html-single/advanced_overcloud_customization/index#sect-Customizing_Hieradata_for_Individual_Nodes there is no mention of this, and this is how its supposed to be done.
