Terraform Support

[GiamPy5]

Is your feature request related to a problem? Please describe.
Allowing Terraform users to use their Terraform code to generates Diagrams as Code.

Describe the solution you'd like
There could be a new option called --terraform to activate the Terraform integration.

Then we could either pass the Terraform Plan out as input parameter:

awsdac terraform/terraform.tfplan.out --terraform

awsdac would then scan the file, and translate it to the diagram.

Describe alternatives you've considered
It's currently not possible to use Terraform and this library right now in a native way.

Additional context
None.
