ZF-5377: Update Zend_Gdata_Gapps to use new feed URLs
The hostname used to access the Google Apps API feeds has changed from www.google.com to apps-apis.google.com. The Zend_Gdata_Gapps classes and associated tests need to be updated to use this when constructing URLs.
Since www.google.com continues serve API requests, existing client versions will continue to work. As a result, this issue is not urgent.
