af5c413abf Focus controller ELB on load balancing apiservers

used to SSH to instances to distribute secrets

77fc14db71 Workaround target pool issue by listing instances as zone/name 
* Instances can be listed by zone/name or self_link URL, but the
provider desires they be in zone/name form, which causes a diff

67e3d2b86e docs: GCE network bandwidth is excellent, even btw zones 
* Remove performance note that the GCE vs AWS network performance
is not an equal comparison. On both platforms, workers now span the
(availability) zones of a region.
* Testing host-to-host and pod-to-pod network bandwidth between nodes
(now located in different zones) showed no reduction in bandwidth

the option, the variable is a holdover from old experiments

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)
