xtables lock was missing. Added new option for oom-score to make sure it's not killed in an OOM situation before regular pods.

Do not override kubelet hostname if cloud_provider is used (#2095)
Starting with Kubernetes v1.8.4, kubelet ignores the AWS cloud
provider string and uses the override hostname, which fails
Node admission checks.

e78562830f Retry kube container removal during upgrade
As we have seen with other containers, sometimes container removal fails on the first attempt due to some Docker bugs. Retrying typically corrects the issue.

e5d353d0a7 contiv network support (#1914)
* Add Contiv support

Contiv is a network plugin for Kubernetes and Docker. It supports
vlan/vxlan/BGP/Cisco ACI technologies. It support firewall policies,
multiple networks and bridging pods onto physical networks.

* Update contiv version to 1.1.4

Update contiv version to 1.1.4 and added SVC_SUBNET in contiv-config.

* Load openvswitch module to workaround on CentOS7.4

* Set contiv cni version to 0.1.0

Correct contiv CNI version to 0.1.0.

* Use kube_apiserver_endpoint for K8S_API_SERVER

Use kube_apiserver_endpoint as K8S_API_SERVER to make contiv talks
to a available endpoint no matter if there's a loadbalancer or not.

* Make contiv use its own etcd

Before this commit, contiv is using a etcd proxy mode to k8s etcd,
this work fine when the etcd hosts are co-located with contiv etcd
proxy, however the k8s peering certs are only in etcd group, as a
result the etcd-proxy is not able to peering with the k8s etcd on
etcd group, plus the netplugin is always trying to find the etcd
endpoint on localhost, this will cause problem for all netplugins
not runnign on etcd group nodes.
This commit make contiv uses its own etcd, separate from k8s one.
on kube-master nodes (where net-master runs), it will run as leader
mode and on all rest nodes it will run as proxy mode.

* Use cp instead of rsync to copy cni binaries

Since rsync has been removed from hyperkube, this commit changes it
to use cp instead.

* Make contiv-etcd able to run on master nodes

* Add rbac_enabled flag for contiv pods

* Add contiv into CNI network plugin lists

* migrate contiv test to tests/files

Signed-off-by: Cristian Staretu <cristian.staretu@gmail.com>

* Add required rules for contiv netplugin

* Better handling json return of fwdMode

* Make contiv etcd port configurable

* Use default var instead of templating

* roles/download/defaults/main.yml: use contiv 1.1.7

Defaults for apiserver_loadbalancer_domain_name (#1993)
* Defaults for apiserver_loadbalancer_domain_name

When loadbalancer_apiserver is defined, use the
apiserver_loadbalancer_domain_name with a given default value.

Fix unconsistencies for checking if apiserver_loadbalancer_domain_name
is defined AND using it with a default value provided at once.

Signed-off-by: Bogdan Dobrelya <bogdando@mail.ru>

* Define defaults for LB modes in common defaults

Adjust the defaults for apiserver_loadbalancer_domain_name and
loadbalancer_apiserver_localhost to come from a single source, which is
kubespray-defaults. Removes some confusion and simplefies the code.

e9f795c5ce Master component and kubelet container upgrade fixes
* Fixes an issue where apiserver and friends (controller manager, scheduler) were prevented from restarting after manifests/secrets are changed. This occurred when a replaced kubelet doesn't reconcile new master manifests, which caused old master component versions to linger during deployment. In my case this was causing upgrades from k8s 1.6/1.7 -> k8s 1.8 to fail
* Improves transitions from kubelet container to host kubelet by preventing issues where kubelet container reappeared during the deployment

0c824d5ef1 Fix kubelet container with alternate Docker data paths
Some time ago I think the hardcoded `/var/lib/docker` was required, but kubelet running in a container has been aware of the Docker path since at least as far back as k8s 1.6.

Without this change, you see a large number of errors in the kubelet logs if you installed with a non-default `docker_daemon_graph`
