Migrate AWS module 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 AWS tutorial and worker pools documentation * Define Terraform and plugin version requirements in versions.tf * Require aws ~> 2.7 to support Terraform v0.12 * Require ct ~> 0.3.2 to support Terraform v0.12

### AWS
|
||||
|
||||
* Migrate from Terraform v0.11 to v0.12.x (**action required!**)
|
||||
* Require `terraform-provider-aws` v2.7+ to support Terraform v0.12
|
||||
* Require `terraform-provider-ct` v0.3.2+ to support Terraform v0.12
|
||||
* Rename `worker` pool module `count` variable to `worker_count` ([#485](https://github.com/poseidon/typhoon/pull/485)) (action required)
|
||||
* `count` will become a reserved variable name in Terraform v0.12
