Permit different levels of horizontal scalability for API vs engine or
conductor processes.  Typically API may need different levels of scale
compared to the engine processes.

Previously, the rabbit container was configured for use in
a k8s cluster. This patch updates the container to run with fig
instead of k8s.

Fig is initially being evaluated to provide container set
functionality. Therefore, the heat template needs to be updated
to support running fig on Kolla nodes. This patch adds the
required directories, files, and commands to run fig and a
RabbitMQ container for testing.

The container spec file had a couple places were nested
lists were used which didn't have the necessary blank
lines before and after.  As such, they didn not render
to HTML correctly.

This patch permits symlinks in the docker build.  Normally docker
does not permit symlinked files in the build context sent to the
docker server.  To work around this problem, a secure directory
is created in /tmp and the container contents are copied to that
directory.  Any symlinks are turned into their non-symlinked
equivalents.

Previously, the kolla heat template was maintained outside of
the project in the larsks/heat-kubernetes repo. This patch adds
the templates to the project's devenv directory. Additionally,
the patch updates the templates and documentation to reflect
the design changes outlined in the following spec:

Previously, the image used for Kolla development
needed to be manually created. This patch adds a
script to automate a consistent, repeatable process
for creating an F21 image used for Kolla development.

This specification proposes using fig (being renamed to compose
soon) to provide single-node multi-container orchestration.  By
using this mechanism, a very simple Ansible Playbook could easily
deploy a single node in to a specific role type - such as a controller
node, a compute node, or a storage node.

This specification further proposes using super-privileged containers
to provide solutions for the upgrade and rollback use cases of an
OpenStack deployment.

When nova-api start and the nova database hasn't yet been created, it
would create it itself, preventing the migration in nova-conductor to
run and making it unable to start. This commit ensures that nova-api
container will not try to steal nova-conductor's job of creating the
nova database.

Nova-scheduler reacts differently to the missing database and simply
exits with a backtrace. This commit also prevents nova-scheduler to
start when the nova database cannot be found.

Fix incorrect test in sh. Bash implements the new test with [[ that
accepts the double equal, however, this is not a bash script. On Debian
and derivates, this will be run by dash.

Make the script portable by not using GNU extensions of xargs.

Call `validate-all-*.sh` scripts whenever possible.

Have bashate look for /usr/bin/env style shebang as well.

Remove useless validate-json.sh file.

This allows Kubernetes to reschedule containers in case a required
variable is missing, for example when the Kubernetes pod is started
before the service.

The checks were cleaned using the following method:
  * remove duplicates
  * remove check for variables that get a default value in the same file
  * check for all variables used in the file
  * check for required services when it is obvious.

Remove git and jq dependency in most scripts, allowing to run them on
latest atomic images, or even distribute Kolla in the form of tarball.

The only remainings of git dependency are in the git pre-commit hook,
and in the image build scripts. We can remove the latter one and have
the scripts running in degraded mode if we really want to.

I opted for a python based approach to finding the top-level directory
for portability, ensuring consistent result on Linux and BSD, including
OSX.

Added the new containers we are supporting.
Kubernetes has updated and kubecfg was replaced with kubectl.

Change-Id: I12b88b856dca150087261f86c674012dcc1b4816

Kubernetes no longer uses 'kubecfg', but rather 'kubectl'.
Therefore, the way that pods and services are being created
needs to be changed.

In order to create a pod, the parameter 'kind' needs to be set
to 'pod' in the yaml file and the api version specified.

The stop script now reads from k8s/{pod,service,replication}/ in order
to stop all the started pods, services, and replication controllers.

The script is a wrapper for the `build-docker-image` script and thus
respond to the same options. It also responds to two additional `--from`
and `--to` options that allows building only images that have changed
between the specified git revisions.

Examples:

    # Build all images contained in docker directory and push new release
    build-all-docker-images --release --push

    # Build only images modified in test-branch along with their children
    build-all-docker-images --from master --to test-branch

It is usually considered good practice for a script to respond to both
short style `-h` and long style `--help` options to display help
message.

This commits adds support for short style `-h` option.
