Dalton Hubble 50db3d0231 Rename CLC files and favor Terraform list index syntax
* Rename Container Linux Config (CLC) files to *.yaml to align
with Fedora CoreOS Config (FCC) files and for syntax highlighting
* Replace common uses of Terraform `element` (which wraps around)
with `list[index]` syntax to surface index errors

Dalton Hubble 1366ae404b Migrate DigitalOcean module from Terraform v0.11 to v0.12
* Replace v0.11 bracket type hints with Terraform v0.12 list expressions
* Use expression syntax instead of interpolated strings, where suggested
* Update DigitalOcean tutorial documentation
* Define Terraform and plugin version requirements in versions.tf
  * Require digitalocean ~> v1.3 to support Terraform v0.12
  * Require ct ~> v0.3.2 to support Terraform v0.12

Dalton Hubble b57273b6f1 Rename internal kube_dns_service_ip to cluster_dns_service_ip
* terraform-render-bootkube module deprecated kube_dns_service_ip
output in favor of cluster_dns_service_ip
* Rename k8s_dns_service_ip to cluster_dns_service_ip for
consistency too

Dalton Hubble 0e71f7e565 Ignore controller user_data changes to allow plugin updates
* Updating the `terraform-provider-ct` plugin is known to produce
a `user_data` diff in all pre-existing clusters. Applying the
diff to pre-existing cluster destroys controller nodes
* Ignore changes to controller `user_data`. Once all managed
clusters use a release containing this change, it is possible
to update the `terraform-provider-ct` plugin (worker `user_data`
will still be modified)
* Changing the module `ref` for an existing cluster and
re-applying is still NOT supported (although this PR
would protect controllers from being destroyed)

Dalton Hubble f034ef90ae Add DigitalOcean AAAA DNS records resolving to workers
* Improve the workers "round-robin" DNS FQDN that is created
with each cluster by adding AAAA records
* CNAME's resolving to the DigitalOcean `workers_dns` output
can be followed to find a droplet's IPv4 or IPv6 address
* The CNI portmap plugin doesn't support IPv6. Hosting IPv6
apps is possible, but requires editing the nginx-ingress
addon with `hostNetwork: true`

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

Sean Swehla 0da7757ef4 Pass Digital Ocean ssh_fingerprints as a list
* Fix digital-ocean module to pass ssh_fingerprints
as a list since the module accepts a list

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
