     1. tf -> only need to update the template file, which appears in the next step
     2. tfstate -> get resource list using private method, format them into resources and return them
     3. As for private methods:
       - module_name_of(<resource>) -> used for module name of terraform to be imported
       - <api method name, e.g. entities_for_policy> -> get the resource info with aws-sdk

     Test Perspective:
     1. Create aws sdk result using stub.
     2. Use the module to generate tf/tfstate.
     3. Compare expected one and generated one.
