Dalton Hubble f3730b2bfa Add Container Linux Config snippets feature
* Introduce the ability to support Container Linux Config
"snippets" for controllers and workers on cloud platforms.
This allows end-users to customize hosts by providing Container
Linux configs that are additively merged into the base configs
defined by Typhoon. Config snippets are validated, merged, and
show any errors during `terraform plan`
* Example uses include adding systemd units, network configs,
mounts, files, raid arrays, or other disk provisioning features
provided by Container Linux Configs (using Ignition low-level)
* Requires terraform-provider-ct v0.2.1 plugin

* Template terraform-render-bootkube's multi-line kubeconfig
output using the right indentation

workers Terraform submodules
* Remove `kubeconfig_*` variables from google-cloud controllers
and workers Terraform submodules

Barak Michener e79088baa0 Add optional cluster_domain_suffix variable
* Allow kube-dns to respond to DNS queries with a custom
suffix, instead of the default 'cluster.local'
* Useful when multiple clusters exist on the same local
network and wish to query services on one another

Dalton Hubble a48dd9ebd8 Require google provider version ~> 1.1
* Require google provider plugin 1.1 or higher which includes fix:
https://github.com/terraform-providers/terraform-provider-google/issues/574
* Remove workaround which statically set the persistent disk name
* Original reasons for workaround in a97df839 or GH #34

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 251a14519f Fix typo in internal template variable name
* ssh_authorized_keys should be ssh_authorized_key to match the user
facing variable which only allows a single SSH authorized key

Dalton Hubble a97df839ea google-cloud: Set disk.device_name to match API default
* Terraform provider "google" plugin releases leave the disk
device_name as "" by default. Recently the API has started to
set a default name "persistent-disk-0". Plan and apply show
all instance groups need to be recreated to "fix" the name
* Impact: Controller and worker instance groups are deleted
and recreated, deleting data on controllers and bringing
down clusters
* Fix: Explicitly set the disk_name to persistent-disk-0 so
that terraform finds no diff needs to be applied.
