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.
The test deployment/rc/pods creation time
is near 2m on slow CI instances with 1 CPU/1.7G RAM.
Increase wait time to allow the post test fail less often.

Fix unreliable waiting for the apiserver to become ready.
Remove logfile mount to align with the rest of static pods
and because containers shall write logs to stdout only.

in the etcd handler, the reload etcd action
was called after ansible waits for etcd to be
up, this means that the health checks which are
called immediately after fail (resulting in the etcd
role always failing and never finishing)
This patch changes the order to move the 'wait for etcd
up' resource after the 'reload etcd resource', ensuring that
the service is up before the health check is called.
* 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'.

Add one more step (task) to containers download/upload sequence -
copy saved .tar containers to ansible host (delegate_to: localhost).
Then upload images to target nodes. It uses synchronize module so
if ansible host (localhost) is the same host as kube-master[0] then
new task causes no issues and the copy to localhost process is
basically skipped.
For Travis CI and GCE, add a naive generator script into a markdown table.
Add GCE/Travis CI matrix docs.
Add CoreOS test cases.
Rework existing cases w/o loosing of coverage.
Rework postinstall tests to support CoreOS as well.
