Move the responsibility to convert from JSON to FileResource into drive_api_operations.
These are two purposes of this change.
1) Resolve the asymmetricity of the JSON and typed C++ conversion.
Now, operation classes take the C++ parameters and format them into JSON.
However, the response is converted in DriveAPIService. This CL resolves the
asymmetricity for FileResource.
2) This is also the preparation of the ResumeUploadOperation implementation.
