* update k8s to 1.13.3

* update README as well

* add to inventory.py script ability to indicate ip ranges

* add test for range2ip function for inventory.py script

some fixes

* add negative test for range2ip function for inventory.py script

Run only commands that apply to the current deployed cluster (only get
calico info and skip weave/flannel when deploying calico, for example).

Add helm release info if helm is deployed

* Define FELIX_KUBENODEPORTRANGES when kube-proxy in ipvs mode

* ensure kube_apiserver_node_port_range is defined

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.

Fixes: #4148

This fixes the issue where if there was a hosts.ini file present in the
inventory directory, then Vagrant would set an incorrect path as
ansible.inventory_path

Fixing an issue where trying to install docker-ce-18.09 on rhel7 nodes (or potentially centos 7) without an enabled extras repo the installation will fail because container-selinux >= 2.9 is required. The check for container-selinux upfront should obviate the need for adding an extras repo if the node is able to find it from another source. (#4161)

* scheduler.alpha.kubernetes.io/critical-pod deprecated since 1.12

Addressing the discussion started in #4064, this PR moves kubeadm and
hyperkube binaries to /usr/local/bin before running them on the master
nodes.

It is to address the case where local_release_dir points to /tmp
(kubespray default) and /tmp is mounted with noexec mode, preventing
any binaries to be run in that partition.

In role "node", we still move kubeadm to bin_dir only on the worker
nodes.

Without this pods cannot communicate with each other by default (broken
networking)

So that binary can be sourced from anywhere - not only github.

Fix epel_enabled and RHEL support in bootstrap-os

Looks like `epel_enabled` was not configured for the epel install in `bootstrap-centos.yml`. Also, there were no conditionals that would trigger bootstrap for RHEL.

Fix docker 18.09.1 systemd service

The `docker-ce` 18.09.1 packaging missed an `After` dependency on containerd in the systemd service. Upstream PR: https://github.com/docker/docker-ce-packaging/pull/290
