Merge larsks/heat-kubernetes to Magnum

In 20150106 IRC meeting, we decide to add two templates to magnum
for creating bays. One for virt and the other is for ironic.

larsks/heat-kubernetes is for virt and we can merge it first.

A Kubernetes cluster with Heat
==============================
These [Heat][] templates will deploy an *N*-node [Kubernetes][] cluster,
where *N* is the value of the `number_of_minions` parameter you
specify when creating the stack.
[heat]: https://wiki.openstack.org/wiki/Heat
[kubernetes]: https://github.com/GoogleCloudPlatform/kubernetes
The cluster uses [Flannel][] to provide an overlay network connecting
pods deployed on different minions.
[flannel]: https://github.com/coreos/flannel
## Requirements
### OpenStack
These templates will work with the Juno version of Heat.
### Guest image
These templates will work with either CentOS Atomic Host or Fedora 21
Atomic. You will need an image dated later than 2015-01-01, or you
will need to create an image that includes Flannel by booting an
existing image, running `atomic ugprade`, and saving the new image.
You can enable the VXLAN backend for flannel by setting the
"flannel_use_vxlan" parameter to "true", but I have run into kernel
crashes using that backend with CentOS 7. It seems to work fine with
Fedora 21.
## Creating the stack
Creating an environment file `local.yaml` with parameters specific to
your environment:
parameters:
ssh_key_name: lars
external_network_id: 028d70dd-67b8-4901-8bdd-0c62b06cce2d
dns_nameserver: 192.168.200.1
server_image: centos-7-atomic-20150101
And then create the stack, referencing that environment file:
heat stack-create -f kubecluster.yaml -e local.yaml my-kube-cluster
You must provide values for:
- `ssh_key_name`
- `external_network_id`
- `server_image`
## Interacting with Kubernetes
You can get the ip address of the Kubernetes master using the `heat
output-show` command:
$ heat output-show my-kube-cluster kube_master
"192.168.200.86"
You can ssh into that server as the `minion` user:
$ ssh minion@192.168.200.86
And once logged in you can run `kubectl`, etc:
$ kubectl get minions
NAME LABELS
10.0.0.4 <none>
You can log into your minions using the `minion` user as well. You
can get a list of minion addresses by running:
$ heat output-show my-kube-cluster kube_minions_external
[
"192.168.200.182"
]
## Testing
The templates install an example Pod and Service description into
`/etc/kubernetes/examples`. You can deploy this with the following
commands:
$ kubectl create -f /etc/kubernetes/examples/web.service
$ kubectl create -f /etc/kubernetes/examples/web.pod
This will deploy a minimal webserver and a service. You can use
`kubectl get pods` and `kubectl get services` to see the results of
these commands.
