Dalton Hubble 9bfb1c5faf Update docs and variable types for worker node_labels
* Document worker pools `node_labels` variable to set the
initial node labels for a homogeneous set of workers
* Document `worker_node_labels` convenience variable to
set the initial node labels for default worker nodes

Valer Cara 99ab81f79c Add node_labels variable in workers modules to set initial node labels (#550)

Dalton Hubble c565f9fd47 Rename worker pool modules' count variable to worker_count
* This change affects users who use worker pools on AWS, GCP, or
Azure with a Container Linux derivative
* Rename worker pool modules' `count` variable to `worker_count`,
because `count` will be a reserved variable name in Terraform v0.12

JordanP 8da17fb7a2 Fix "google_compute_target_pool.workers: Cannot determine region"
If no region is set at the Google provider level, Terraform fails to
create the google_compute_target_pool.workers resource and complains
with "Cannot determine region: set in this resource, or set provider-level 'region' or 'zone'."

This commit fixes the issue by explicitly setting the region for the
google_compute_target_pool.workers resource.

Dalton Hubble aaa8e0261a Add Google Cloud worker instances to a target pool
* Background: A managed instance group of workers is used in backend
services for global load balancing (HTTP/HTTPS Ingress) and output
for custom global load balancing use cases
* Add worker instances to a target pool load balancing TCP/UDP
applications (NodePort or proxied). Output as `worker_target_pool`
* Health check for workers with a healthy Ingress controller. Forward
rules (regional) to target pools don't support different external and
internal ports so choosing nodes with Ingress allows proxying as a
workaround
* A target pool is a logical grouping only. It doesn't add costs to
clusters or worker pools

Dalton Hubble 46196af500 Remove Haswell minimum CPU platform requirement
* Google Cloud API implements `min_cpu_platform` to mean
"use exactly this CPU"
* Fix error creating clusters in newer regions lacking Haswell
platform (e.g. europe-west2) (#438)
* Reverts #405, added in v1.13.4
* Original goal of ignoring old Ivy/Sandy bridge CPUs in older regions
will be achieved shortly anyway. Google Cloud is deprecating those CPUs
in April 2019

Dalton Hubble ba4c5de052 Set the Google Cloud minimum CPU platform to Intel Haswell
* Intel Haswell or better is available in every zone around the world
* Neither Kubernetes nor Typhoon have a particular minimum processor
family. However, a few Google Cloud zones still default to Sandy/Ivy
bridge (scheduled to shift April 2019). Price is only based on machine
type so it is beneficial to opt for the next processor family
* Intel Haswell is a suitable minimum since it still allows plenty of
liberty in choosing any region or machine type
* Likely a slight increase to preemption probability in a few zones,
but any lower probability on Sandy/Ivy bridge is due to lower
desirability as they're phased out

* Update coreos/pod-checkpointer to strip affinity from
checkpointed pod manifests. Kubernetes v1.12.0-rc.1 introduced
a default affinity that appears on checkpointed manifests; but
it prevented scheduling and checkpointed pods should not have an
