Now kubernetes image is 1.0.6 and written in so many file.
It is difficult to modify the parameter when we need to change
it.
The patch make the value united a variable.

Allow configuring Flannel with 3 different backends
Magnum deploys k8s/swarm over a dedicated neutron private network,
possibly using flannel. Flannel's `host-gw` backend gives the best
performance in this topopolgy (private layer2): no packet processing
overhead, no reduction to MTU, scales to many hosts as well as the
alternatives. The performance difference is significant, see bug for
performance numbers for the 3 backend options.
Note that part of this change involves relaxing the minion IP spoofing
rules to allow traffic from all dynamically-allocated flannel subnets.
This is morally equivalent to what we were doing previously with
encapsulation - only now neutron is able to see the inner IP header
directly.
This patch repurposes the label "flannel_use_vxlan" when the network
driver is flannel.
1. Rename the label flannel_use_vxlan to flannel_backend
2. Redefine the value of this label from "yes/no"
to "udp/vxlan/host-gw"
For example, to create a bay model with flannel as network driver:
--network-driver flannel --labels flannel_backend=host-gw
Other backend options are udp and vxlan.

This patch follows the CoreOS guidance for kubernetes:
https://coreos.com/kubernetes/docs/latest/getting-started.html
CoreOS doesn't support multi-part mime user-data, so we cannot pack
multiple scripts into one (which we did in Atomic). The major work of
this patch is to wrap each cloud-init script with a systemd unit,
which will be executed one-by-one at the first boot.
Note that this patch only enable a basic CoreOS support. Advanced
features (i.e. TLS, Cinder volume, HA, external load balancing) are
not included. These features need to be ported from Atomic as a
future work.

1. kubelet can automatically register nodes, so we don't need to
register nodes.
2. When we remove a node from the cluster, the nova instance is
terminated. So the instance has no stop process to run unregister
script. Heat has a spec [1] to add stop deletion policy now. After
this function is merged, I will add unregister script back.

Rename heat-kubernetes to kubernetes, heat-mesos to mesos,
docker-swarm to swarm in templates. We use heat templates and
no other methods, so I think it is unnecessary to add heat before
coe. kubernetes, mesos, swarm are better than
heat-kubernetes, heat-mesos, docker-swarm.

Kubernetes service provides the LoadBalancer feature
This is supported through an OpenStack plugin in Kubernetes code.
Enabling this feature requires configuring the cluster properly for
Kubernetes to interface with Neutron. Kubernetes backend will then
create the Neutron load balancer pool, members, VIP and monitor,
and manage the pool members as pods are added/removed from the
service.
This patch updates the CoreOS heat templates for host name and
network name that match what Kubernetes code expects.
The scripts used by these templates are in the patch for Fedora Atomic
which this patch has a dependency on.

Seems jenkins default image API version is 2, image v2 version
not support use name as image-show. I tried latest devstack, it
calls v2 API. So in jenkins jobs let's use v1 version now.
In addition, specify the mountpoint parameter on VolumeAttachment
resource. Heat used to allow missing of this parameter but it is
not the case anymore.

According to Heat documentation, AWS::CloudFormation::WaitCondition
timeout attribute should be a number but magnum templates use strings:
master_wait_condition:
type: "AWS::CloudFormation::WaitCondition"
properties:
Handle:
get_resource: master_wait_handle
Timeout: "6000"
This change replaces string timeouts ("6000") by number timeout (6000).

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.
