AWS Provider - default tags

[taktakpeops]

Describe the bug

Hello,

When using the AWS provider, the configuration property doesn't allow setting up a map as value for defining the default_tags.tags.

To Reproduce

Steps to reproduce the behavior:

1. Apply the following provider definition:

apiVersion: terraform.appvia.io/v1alpha1
kind: Provider
metadata:
  name: aws
spec:
  configuration:
    assume_role:
      role_arn: "arn:aws:iam::${some_account_id}:role/${some_role}"
    default_tags:
      tags:
        Environment: "dev"
        Name: "${some_name}"
        Region: "${some_region}"
        CostCenter: "${some_cost_center}"
        Terraform: true

2. Deploy a CloudResource using the provider above, here is the provider.tf produced with the controller inside of the secret with all the config:

provider "aws" {
  
  assume_role {
    role_arn = "arn:aws:iam::${some_account_id}:role/${some_role}"
  }
  
  default_tags {
    tags {
      CostCenter  = "${some_cost_center}"
      Environment = "dev"
      Name        = "${some_name}"
      Region      = "${some_region}"
      Terraform   = true
    }
  }
  
}

3. When the plan runs, it generates the following error:

Error: Unsupported block type

  on provider.tf line 8, in provider "aws":
   8:     tags {

Blocks of type "tags" are not expected here. Did you mean to define argument
"tags"? If so, use the equals sign to assign it a value.

Expected behavior

When the parsing happens, default_tags.tags should be seen an argument, rather than a block. I think the logic for dealing with it should be implemented in here: https://github.com/appvia/terranetes-controller/blob/master/pkg/utils/terraform/utils.go#L136

I would expect such output for the provider.tf:

provider "aws" {
  
  assume_role {
    role_arn = "arn:aws:iam::${some_account_id}:role/${some_role}"
  }
  
  default_tags {
    tags = {
      CostCenter  = "${some_cost_center}"
      Environment = "dev"
      Name        = "${some_name}"
      Region      = "${some_region}"
      Terraform   = true
    }
  }
  
}
