Dalton Hubble 85e6783503 Recommend Container Linux images with Docker 17.09
* Container Linux stable and beta now provide Docker 17.09 (instead
of 1.12). Recommend images which provide 17.09.
* Older clusters (with CLUO addon) auto-update node's Container Linux version
and will begin using Docker 17.09.

Dalton Hubble 159443bae7 addons: Add better alerting rules to Prometheus manifests
* Adapt the coreos/prometheus-operator alerting rules for Typhoon,
https://github.com/coreos/prometheus-operator/tree/master/contrib/kube-prometheus/manifests
* Add controller manager and scheduler shim services to let
prometheus discover them via service endpoints
* Fix several alert rules to use service endpoint discovery
* A few rules still don't do much, but they default to green

Dalton Hubble 26a291aef4 Remove controller_preemptible option on Google Cloud
* Controller preemption is not safe or covered in documentation. Delete
the option, the variable is a holdover from old experiments
* Note, worker_preemeptible is still a great feature that's supported

Dalton Hubble 6300383b43 Change worker managed instance group to span zones in region
* Change Google Cloud module to require the `region` variable
* Workers are created in random zones within the given region
* Tolerate Google Cloud zone failures or capacity issues
* If workers are preempted (if enabled), replacement instances can
be drawn from any zone in the region, which should avoid scheduling
issues that were possible before if a single zone aggressively
preempts instances (presumably due to Google Cloud capacity)
