AWS iops attribute is only valid for io1 and io2 type EBS volumes, not gp2, sc1 and st1 types.

General information:

• Operating System: Arch Linux
• Terracognita version / tag: v0.5.1
• Did you build Terracognita from sources or did you use the Docker image: I downloaded https://github.com/cycloidio/terracognita/releases/download/v0.5.1/terracognita-linux-amd64.tar.gz

Describe the bug:

A clear and concise description of what the bug is.

Description: When TerraCognita generates Terraform code for AWS EBS volume types gp2, sc1 and st1 the output includes an iops attribute which is invalid syntax for using with terraform apply.

https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ebs_volume
iops - (Optional) The amount of IOPS to provision for the disk. Only valid for type of io1 or io2.

Additional context

Expected: Import AWS resources using TerraCognita and be able to use the resulting Terraform code without modification with terraform apply.

Actual: TerraCognita will output invalid Terraform code that cannot be used with terraform apply as-is.

Reproducing:

1. Launch EC2 instance.
2. Import via TerraCognita (example: terracognita aws -i aws_instance --access-key "$(awk '/aws_access_key_id/ {print $3}' ~/.aws/credentials)" --secret-key "$(awk '/aws_secret_access_key/ {print $3}' ~/.aws/credentials)" --region us-east-2 --hcl instance.tf)
3. Terminate EC2 instance (or don't, it's not essential).
4. Run terraform apply
5. Get Error: error creating resource: iops attribute not supported for root_block_device with volume_type gp2
6. The error is fatal; terrform apply will not not launched any resources.

Add any other context about the problem here.

Running terraform plan will not report the error in the Terraform code.

The iops = "100" (excerpted from /instance.tf generated above) is invalid syntax for terraform apply:

  root_block_device {
    delete_on_termination = true
    iops                  = 100
    volume_size           = 8
    volume_type           = "gp2"
  }

I tested with Terraform versions v0.12.29 and v0.14.2.
