v0.7.0

Use `terraform-provider-utils` Terraform provider for the module and all submodules @aknysh (#8)

what

• Use terraform-provider-utils Terraform provider for the module and all submodules
• Add examples/stacks example
• Update the module and all submodules to the latest context.tf and terraform-null-label

why

• Speed up the stack processing (especially for SaaS as Spacelift where all components from all stacks are processed at once)
• Return vars and backend configurations for all Terraform and helmfile components for all the provided stacks at the same time
• Support unlimited imports and unlimited levels of imports in YAML configs

test

terraform config

NOTE: In the example below, using version 0.2.0 of the terraform-provider-utils provider, terraform apply finishes in about a second processing all the Terraform and helmfile components from the 4 stacks (including processing/deep-merging of all imports for all stacks, and deep-merging of vars and backend from different config sections)

    module "stacks" {
      source = "cloudposse/stack-config/yaml"
      # version     = "x.x.x"
    
      stack_config_local_path = "./stacks"

      stacks = [
        "uw2-dev",
        "uw2-prod",
        "uw2-staging",
        "uw2-uat"
      ]
    }
