So far we've been using virtlogd running on the host, we should now be
using virtlogd from a container.

A recent commit [1] change how docker is installed and configured on
the overcloud nodes, from a cloud-init script to a proper puppet
profile in puppet-tripleo but forgot to enable the docker service on
the compute nodes.

This patch implements a new docker deployment architecture that
should us to install docker services in a stepwise manner alongside
of baremetal puppet services. This works by using Yaql to select
docker specific services (docker/services/*.yaml) vs the puppet
specific ones and then applying the selected Json to relevant Heat
software deployments for docker and baremetal puppet in a stepwise
fashion.
Additionally the new architecture
leverages new composable services interfaces from Newton to
allow configuration of per-service container configuration
sets (directories that are bind mounted into kolla containers) by
using the Kolla containers themselves. It does this by spinning up
a throw away "configuration only" version of the container being
configured itself, then running the puppet apply in that container and
copying the generated config files into /var/lib/config-data. This
avoids having to install all of the OpenStack dependency packages
in the heat-agent-container itself (our previous approach) and should
allow us to configure a much wider variety of container config files
that would otherwise be impossible with the previous shared approach.
The new approach (combined) should allow us to configure containers in
both the undercloud and overcloud and incrementally add CI coverage to
services as we containerize them.
