Implement new methods other than ContinueGetResourceList for FakeDriveService.

This CL implements five newly introduced methods on FakeDriveService.
The implementation of ContinueGetResourceList, the remaining method, needs
slightly more changes, so it will be done in another CL.
The new methods will be used for testing of replacing GetResourceList method.
