Terraform 0.12 broke compatability and this could result in data loss
if we deleted the etcd volumes. Document the procedure to fix the
tfstate, and require an env var to be passed to avoid accidental data
loss.
The old code made the incorrect assumption that the NLB's list of TargetGroup tasks is in the same order as the NLB's list of listeners for their associations.
Because the model adds them in opposite orders this resulted in the TLS listener being forwarded to the TCP TG and vice versa.
This updates the terraform and cloudformation generation code to search the NLB's list of target groups by name for the target group that should be associated with the listener.
This matches the logic used in the "direct" target.
Similar to how we can configure coreDNS image we will like to configure
cluster Proportional autoscaler so we can use our internal docker
registry rather than gcr.io.
- Resources
We enable users to set their desired capacity for cluster-autoscaler addon.
There are edge cases, especially in big clusters, where autoscaler needs
to reconcile a large number of objects thus may need increased memory or
increased cpu to avoid saturation.
- Metrics
Cluster autoscaler provides valuable insights for monitoring capacity
allocation and scheduling aspects of a cluster. In this commit, we
add proper annotation on deployment to enable Prometheus scrape metrics.
We also bump patch version of container images.

We were adding to the ServerGroup without a mutex, so we introduce a mutex.
Also introduce some defense against the member list changing once
we've observed it, though this is already enforced by GetDependencies.
Upstream bind mounts /var/lib/kubelet with exec, dev and suid
permissions, because emptyDirs end up inheriting these permissions.
Similarly, /home/kubernetes/flexvolume needs exec permission to
support flexdrivers.
