Transforms the SAM defined Tags into the form CloudFormation is expecting.

SAM Example:
    ```
    ...
    Tags:
      TagKey: TagValue
    ```


CloudFormation equivalent:
      - Key: TagKey
        Value: TagValue
    ```

:param resource_tag_dict: Customer defined dictionary (SAM Example from above)
:return: List of Tag Dictionaries (CloudFormation Equivalent from above)
