In the OpenStack deployment with Octavia service enabled, the octavia
service should be used not only for master nodes high availability, but
also for k8s LoadBalancer type service implementation as well.

Currently, there is no guarantee to make sure all nodes of one cluster are
created on different compute hosts. So it would be nice if we can create
a server group and set it with anti-affinity policy to get a better HA
for cluster. This patch is proposing to create a server group for master
and minion nodes with soft-anti-affinity policy by default.

In the drivers section of magnum.conf add openstack_ca_file.
This file is expected to be a CA Certificate OR CA bundle
which will be passed on every node and it will be installed
on the host's CA bundle.
Update devstack plugin to use the ssl bundle if tls-proxy is
enabled.
Install the CA for drivers:
k8s_coreos_v1
k8s_fedora_atomic_v1
k8s_fedora_ironic_v1
mesos_ubuntu_v1
swarm_fedora_atomic_v1
swarm_fedora_atomic_v2
Add doc in troubleshooting-guide.
Add release notes.

Added configuration parameter, verify_ca, to magnum.conf with default
value of True. This parameter is passed to the heat templates to
indicate whether the cluster nodes validate the Certificate Authority
when making requests to the OpenStack APIs (Keystone, Magnum, Heat).
This configuration parameter can be set to False to disable CA
validation.

The instance type of servers at the moment can become quite long
due to the Heat autogenerated names. This patch cleans up the names
so that they are shorter yet contain all the info needed to be able
to know where they belong to.

This change introduces default recommended values for Kubelet on CoreOS:
- Usage of CNI (Container Networking Interface) with Flannel
- Update deprecated Kubelet Args (--config)
- Bind mount recommended CoreOS folders in Kubelet
It also introduces a new parameter: CONTAINER_RUNTIME which will allow to
switch between rkt and docker as container runtime. For now only docker
is used.

Parent commit allow custom secure HYPERKUBE_IMAGE_REPO (which can also
be a local registry). Here we implement INSECURE_REGISTRY_URL which
allow settings custom insecure registry for Kubernetes infra components.
It also enable the insecure registry for Docker daemon.

Introduce HYPERKUBE_IMAGE_REPO variable which is set to CoreOS
hyperkube by default. Also remove "_coreos.0" from script as it can be a
different build number. This number should be included in the kubernetes
version parameters and not in scripts.
With this, it is possible to use any combination of hyperkube image with
any tags. by default we use the CoreOS one.

Multiple variables names where used in different fragments. This commit
makes KUBE_CERTS_PATH and HOST_CERTS_PATH hardcoded values in heat-params
fragment and use them inside fragments instead of hardcoded value and
different variables names

With this patch following are done:-
- Configure Etcd with TLS support
Configure Following to commuicate with TLS enabled Etcd:-
- Flannel
Etcd also listens at http://127.0.0.1:2379, so on master nodes
etcdctl can communicate without using certificates.
if TLS_DISABLED="True" then TLS is not enabled for etcd.

Since we have seperate template files to different driver directory, we
can cleanup -coreos suffix from template.
1. Remove unused shell scripts.
2. Remove kube-examples.yaml and kube-user.yaml which is never used.
