* Make local volume provisioner dir mode a variable

I need to change this for Nagios monitoring. Others may
need to as well. Had to close previous commits, sorry for
the spam.

* Add support for arm images for hyperkube, kubeadm and cni_binary

* Add dummy etcd checksum for arm

This commit adds dummy etcd checksum for arm to avoid "no attribute" error
during setup.

* Add etcd host assert check

* Add 1.13.4 checksums of kubeadm and hyperkube for arm

* Update checksums of kubeadm and hyperkube for arm

* Add dummy checksums for calicoctl_binary_checksums dict

* disable gather_facts because it causes tests to fail

* Remove architecture check for etcd, due to unable to run tests

... kube-node or etcd is empty" task
As a assert must be ignored if ignore_assert_errors is true

Circumvented one false positive from ansible-lint
Moved a block of jinja magic into its own variable

* Use K8s 1.14 and add kubeadm experimental control plane mode

This reverts commit d39c273d.

* Cleanup kubeadm setup run on first master

* pin kubeadm_certificate_key in test

* Remove kubelet autolabel of kube-node, add symlink for pki dir

Change-Id: Id5e74dd667c60675dbfe4193b0bc9fb44380e1ca

This reverts commit 31650862.

* Use Kubernetes 1.14 and experimental control plane support

* bump to v1.14.0

* Added generic CNI network plugin

* Added CNI network plugin documentation

* added necessary fix

Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.

This reverts commit ea7a6f1c.

This change modified the certs dir for Kubernetes, but did not move the directories for existing clusters.

* Remove hard dependence on facts for all nodes

* Update main.yaml

* Update main.yaml

* fact gathering should run only once per node
* eliminate ansible version check, it is at the beginning of each
  playbook

check kube_pods_subnet and kube_service_addresses to valid ip network range, not single ip address (#4188)

This PR ensures that the e2fsprogs and xfsprogs packages are
installed on all Kubernetes nodes and that the packages are
the latest versions. It also ensures that the nodes can
create XFS filesystems when necessary, since not all distros
install xfsprogs by default.

e2fsprogs - ext2/ext3/ext4 file system utilities
xfsprogs - Utilities for managing the XFS filesystem

Avoid waiting forever for this task that should be very quick.
