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
