Implement new methods to replace GetResourceList on GData WAPI.

This CL implements the new methods in GDataWapiService. Because the GData WAPI
will be deprecated, so instead of splitting GetResourceListOperation, keeping
it as is but set some default parameters in GDataWapiService.
The new methods are not used yet, but will be soon used.

BUG=160932
TEST=Ran unit_tests
