Currently, the terraform script in contrib
adds etcd role as a child of k8s-cluster in
its generated inventory file.
This is problematic when the etcd role is
deployed on separate nodes from the k8s master
and nodes. In this case, this leads to failures
of the k8s node since the PKI certs required for
that role have not been propogated.
* Add download_localhost for the download_run_once mode, which is
use the ansible host (a travis node for CI case) to store and
distribute containers across cluster nodes in inventory.
Defaults to false.
* Rework download_run_once logic to fix idempotency of uploading
containers.
* For Travis CI, enable docker images caching and run Travis
workers with sudo enabled as a dependency
* For Travis CI, deploy with download_localhost and download_run_once
enabled to shourten dev path drastically.
* Add compression for saved container images. Defaults to 'best'.

[03e162b] Update OWNERS
[c7b00ca] 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.
[2778ac6] 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
before kubelet is up.
