This updated scenario ensures deployment still passes without
having any group_vars available.

* Fix broken CI jobs

Adjust image and image_family scenarios for debian.
Checkout CI file for upgrades

* add debugging to file download

* Fix download for alternate playbooks

* Update ansible ssh args to force ssh user

* Update sync_container.yml

Use image family for picking latest coreos image
Update python deps

Also fix usage of failed_when and handling exit code.

New files: /etc/kubernetes/admin.conf
           /root/.kube/config
           $GITDIR/artifacts/{kubectl,admin.conf}

Optional method to download kubectl and admin.conf if
kubeconfig_lcoalhost is set to true (default false)

* just use public_ip in creating gce temporary waitfor hosts

* Update create-gce.yml

* Enable HA deploy of kubeadm

* raise delay to 60s for starting gce hosts

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.

New deploy modes: scale, ha-scale, separate-scale
Creates 200 fake hosts for deployment with fake hostvars.

Useful for testing certificate generation and propagation to other
master nodes.

Updated test cases descriptions.

Revert preemptible GCE instances for CI as they are too
much of UNREACHABLE. Later we could return to them after
figured out how to mitigate preepted instances with
automated CI retries.

[03e162b3] Update OWNERS
[c7b00cae] Use tar+register instead of copy/slurp for distributing tokens and certs

Related bug: https://github.com/ansible/ansible/issues/15405

Uses tar and register because synchronize module cannot sudo on the
remote side correctly and copy is too slow.

This patch dramatically cuts down the number of tasks to process
for cert synchronization.
[2778ac61] Add new var skip_dnsmasq_k8s

If skip_dnsmasq is set, it will still not set up dnsmasq
k8s pod. This enables independent setup of resolvconf section
