Not sure if it's worth sharing GetAccountMetadataOperation in this way.
GetAccountMetadataOperation is fairly small. Might be cleaner to create a
separate class.

btw, gdata_operations.cc has been getting big. we might want to split this...

gdata_operations.cc split is done:

And I intend to have another classes for Drive API calls.
