Add/update docs for asset_dir and kubeconfig usage

* Original tutorials favored including the platform (e.g.
google-cloud) in modules (e.g. google-cloud-yavin). Prefer
naming conventions where each module / cluster has a simple
name (e.g. yavin) since the platform is usually redundant
* Retain the example cluster naming themes per platform

For existing Typhoon v1.14.2 or v1.14.3 clusters, edit the Typhoon `ref` to first SHA that introduced Terraform v0.12 support (`3276bf587850218b8f967978a4bf2b05d5f440a2`). The aim is to minimize the diff and convert to using Terraform v0.12.x. For example:
```tf
module "bare-metal-mercury" {
module "mercury" {

With Terraform v0.12, Typhoon clusters no longer require the `providers` block (unless you actually need to pass an [aliased provider](https://www.terraform.io/docs/configuration/providers.html#alias-multiple-provider-instances)). A regression in Terraform v0.11 made it neccessary to explicitly pass aliased providers in order for Typhoon to continue to enforce constraints (see [terraform#16824](https://github.com/hashicorp/terraform/issues/16824)). Terraform v0.12 resolves this issue.
