Necessary to persist this directory for host-local IPAM used by Canal
Add pre-upgrade task to copy /var/lib/cni out of old kubelet.

Canal runs more pods and upgrades need a bit of extra
room to load new pods in and get the old ones out.

Allows config changes made by Ansible to restart dnsmasq deployment

Graceful upgrades require 3 nodes
Drain now has a command timeout of 40s

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

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

etcd is crucial part of kubernetes cluster. Ansible restarts etcd on
reconfiguration. Backup helps operator to restore cluster manually in
case of any issues.
