Scripts are the core of Magnum for COE deployment. To be more
clear and consistent, two changes proposed in this patch:
1. Rename network related script to xxx-flannel-xxx given they
are all for flannel and now we have calico driver.
2. Adding .sh for some scripts to be consistent with others.

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.
Change-Id: Ib61f59507510253794a4780a91e49aa6682c8039
Closes-Bug: #1770133
Currently, the default k8s version in Magnum is v1.7.4, but based on the
deprecation policy of k8s. It will be deprecated at March 2018, see
https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/
So it would be nice to change the default k8s version to latest.

Due to a few several small connected patches for the
fedora atomic driver, this patch includes 4 smaller patches.
Patch 1:
k8s: Do not start kubelet and kube-proxy on master
Patch [1], misses the removal of kubelet and kube-proxy from
enable-services-master.sh and therefore they are started if they
exist in the image or the script will fail.
https://review.openstack.org/#/c/533593/
Closes-Bug: #1726482
Patch 2:
k8s: Set require-kubeconfig when needed
From kubernetes 1.8 [1] --require-kubeconfig is deprecated and
in kubernetes 1.9 it is removed.
Add --require-kubeconfig only for k8s <= 1.8.
[1] https://github.com/kubernetes/kubernetes/issues/36745
Closes-Bug: #1718926https://review.openstack.org/#/c/534309/
Patch 3:
k8s_fedora: Add RBAC configuration
* Make certificates and kubeconfigs compatible
with NodeAuthorizer [1].
* Add CoreDNS roles and rolebindings.
* Create the system:kube-apiserver-to-kubelet ClusterRole.
* Bind the system:kube-apiserver-to-kubelet ClusterRole to
the kubernetes user.
* remove creation of kube-system namespaces, it is created
by default
* update client cert generation in the conductor with
kubernetes' requirements
* Add --insecure-bind-address=127.0.0.1 to work on
multi-master too. The controller manager on each
node needs to contact the apiserver (on the same node)
on 127.0.0.1:8080

To pass the e2e conformance tests, coredns needs to
be configured with POD-MODE verified. Otherwise, pods
won't be resolvable [1].

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.

Allow any value to be passed on the docker_storage_driver field by turning it
into a StringField (was EnumField), and remove the constraints limiting the
values to 'devicemapper' and 'overlay'.
Change the docker storage setup to have a generic setup for all drivers with
the exception of 'devicemapper', which keeps its own specific storage config
function. For all others, do the same we already did for overlay (with two
cases for usage of a cinder volume or not) and simply set the storage driver
in the docker configuration to the value provided in the cluster template.

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.

Separate the tag from which to pull from the kubernetes version.
With the current state the tag and the version happen to be the
the same. But, it is not decided yet in the fedoraproject how the
images are going to be tag. Finally, operators might want to try
their own container images with custom tags.

Previously the master's private IP address was not pushed through to the
minion configuration when the load balancer is disabled as the heat
templates were not wired up in this case. This change resolves that
issue and makes it possible for security groups to be applied to the
master and minion ports.

Profit from the default cAdvisor deployed by k8s to deploy the
remaining monitoring stack on top, made of node-exporter,
Prometheus and Grafana.
Node-exporter is ran as a normal pod through a manifest, while
Prometheus and Grafana are deployments with 1 replica.
Prometheus has compliance with Kubernetes, so the discovery of
the nodes and other k8s components is configured directly in
Prometheus configuration.

docker-1.12.6-5.git037a2f5.fc25.x86_64
flannel-0.5.5-8.fc25.x86_64

The ironic image contains exactly the same packages.
* For this upgrade the upstream image is used, which is
uploaded here [1].
* Minor changes for flannel and docker-storage-setup
were needed.
* The image will be built in the CI and uploaded to
tarballs.openstack.org as soon as possible.
* Ironic image [2].
Notes:
* docker-storage-setup config changes were needed because in
the previous images it was disabled and it was started by us.
* We can have selinux enables in containers since the images
have kernel 4.9.x.

In the swarm_atomic and k8s_atomic drivers container images are
stored in a dedicated cinder volume per cluster node. It is
proven that this architecture can be a scalability bottleneck.
Make the use of cinder volumes for container images and opt-in
option. If docker-volume-size is not specified no cinder
volumes will be created. Before, if docker-volume-size wasn't
specified the default value was 25.
To use cinder volumes for container storage the user will
interact with magnum as before, (meaning the valid values are
integers starting from 1).

work I'm currently doing.
With stevedore, we can choose only one driver based on the

then choose an implementation bases on server_type.
