This adds a very basic structure to begin supporting ansible in Kolla.
Ansible can support complete idempotency, but wrapping docker-compose
does not allow idempotency at this time. These playbooks will be
extended to compensate for that in future patches.

When using ';' this can allow the previous command to fail and while the
docker build proceeds without realizing a command failed. Switching to
'&&' allows the exit code to make it to the docker build command and the
build to fail appropriately.

Adds the neutron-linuxbridge-agent to the neutron container set.

This patch builds pam with no auditing.  This allows the images to
operate on Ubuntu 14.04 which contain a kernel bug and have not been
updated.

Each container requires a set of environment variables be declared
so that it can function in a minimal setting.  This doc will
provide a list of those environment var for each container.

Data volumes are busted in docker master 1.6-rc1.  Need to use a special
branch in order for docker to work.

Previously, nova enabled_apis was hard coded and metdata_host
was using PUBLIC_IP param instead of exposing an individual
param.

Extending these params and creating a separate compose yml that
includes compute/libvirt/network/api is required to support
nova network multi_host.

Previously, eth0 was set as the nova flat interface. This
interface is used to bridge VM traffic between instances and
should not have an IP. It's a problem when you associate an
interface with an IP to the FLAT_INTERFACE.

Previously, Heat was not allowing the necessary TCP ports for
RabbitMQ and MariaDB to Kolla nodes.

A few errors in the dev doc were causing problems with deploying
a dev env. The dev dos has been updated with the correct steps for
prep'ing a host for running Kolla. Additionally, wording has been
added to reference the Heat template for dev env deployment.

Updates the following:

1. Replaces Docker copr pkgs with binary
2. Updates docs
3. Adds compose from sdake GH repo
4. Adds required ebtables kernel module for nova-network
5. Adds container net/subnet info required for correct nova
networking functionality.
6. Consolidates pkgs installs from get-image script to the
heat template.

Heat container is having trouble accessing heat meta data.
Heat needs to have HEAT_CFN_API_SERVICE_HOST set in order
to properly receive meta data.

A data container is meant to operate without bindmounts.

Change-Id: I2624a63fd75db7ed8050054c17e19885f8a7ac8a

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.

Use docker-compose with the stop operation rather than cleanup-containers -f.

docker-compose master now requires 1.18 API, which is only available

This change was lost in 888bb9cc.
Both modprobe and setenforce require root, so I think this is a good
sanity check.
