As a restructure, nothing is changed from the original behaviour and
naming despite the file structure changing. The symlinks to build had
to be updated generating lots of "deleted" and "new_file".

The new structure is:

docker/${base_distro}/${type}/${container}

base_distro == centos, ubuntu, fedora, etc
type == source, binary, rdo

type rdo is a symlink to binary for backwards compatibility

Two new flags are added to the build-all script to support the ability
to support different base distros and a flag to support binary or source
containers.

There are several added folders that are empty to hold the directory
structure for future containers of these types.

To use a prefix other than centos-rdo- you can set PREFIX in the toplevel
directory .buildconf file

This represents making build-docker-images --release build
with the icehouse tag and causes docker-compsoe to pull from
the icehouse tag.

Partially-implements: blueprint port-kilo

<title>Make nova-compute-network use a data volume container</title>

A data volume container is far superior to bind mounting the
host's shared directories.  It preserves the idempotency,
immutability and declarative properties of the containers.

The way this works in practice is that a data volume container is
created.  Then when the containers start they use LVM to access
the filesystem where /var/lib/docker is contained.  Then the
container startup logic bindmounts the data volume stored on the
host filesystem in /var/lib/docker/vfs/dir/ID.  This prevents
people with access to the host operating system from damaging
the contents of the data container.

It does mean that now we must use tools/stop to stop our containers
rather than tools/cleanup-containers -f.

This is a containers best practice.  For more details see:

https://docs.docker.com/userguide/dockervolumes/

Big credit goes to Danyeon Hansen for seeding this idea in the
mariadb containers.

Note occasionally docker-compose start/stop seems to not want to stop
a container.  This bug needs to be addressed upstream separately
from our utilization of this best practice.
