In kubernetes 1.6 ClusterFirstWithHostNet was added as an option. In
accordance to it kubelet will generate resolv.conf based on own
resolv.conf. However, this doesn't create 'options', thus the proper
solution requires some investigation.

This patch sets the same resolv.conf for kubelet as host

Fix multiline condition for k8s check certs

pin ansible to version 2.2.1.0

Useful at scale when 1 or 2 noes my fail and you can proceed with
the majority and go back and fix the others later.

Fixes #1190

add iptables --flush to reset role

Bump calico policy controller version

Fix multiline when condition in sync_certs task

Folded style in multiline 'when' condition causes error with
unexpected ident. Changing it to literal style should fix
the issue.

Closes #1190

1169 - fix docker systemd unit

ansible 2.2.2.0 has an [issue]() that causes problems for kargo:

```
(env) kargo ᐅ env/bin/ansible-playbook upgrade-cluster.yml 
ERROR! Unexpected Exception: 'Host' object has no attribute 'remove_group'
```

Pinning ansible to 2.2.1.0 resolved this for me.

Refactor etcd role

Fix markdown of heading in README

- Run docker run from script rather than directly from systemd target
- Refactoring styling/templates

Latest released version of kube-policy-controller
contains important bug fixes and should be used
by default.

Update roadmap.md

replace non-breakable space with regular space

Add missing defaults

Fixes for AWS Terraform Deployment

Non-brekable space is 0xc2 0xa0 byte sequence in UTF-8.

To find one:

    $ git grep -I -P '\xc2\xa0'

To replace with regular space:

    $ git grep -l -I -P '\xc2\xa0' | xargs sed -i 's/\xc2\xa0/ /g'

This commit doesn't include changes that will overlap with commit f1c59a91.

Use checksum of dnsmasq config to trigger updates of dnsmasq

Change wait for dnsmasq to skip if there are no kube-nodes in play

Allows config changes made by Ansible to restart dnsmasq deployment

Add KVM hypervisor playbook to contrib

Disable download_run_once and download_localhost for most CI scenarios

The docker-network environment file masks the new values
put into /etc/systemd/system/docker.service.d/flannel-options.conf
to renumber the docker0 to work correctly with flannel.

Optional Ansible playbook for preparing a host for running Kargo.
This includes creation of a user account, some basic packages,
and sysctl values required to allow CNI networking on a libvirt network.

Also changed unnecessary delay to a max timeout (now defaulting to 1s sleep
between tries)

Also rename play_hosts to ansible_play_hosts

This adds time to deployment, so we should only test it sparingly during
daily master.

Backup etcd

Bump CoreOS stable to latest version

Make reset check on idempotency check optional

Add helm deployment
