Drive pager usage currently showcases strong coupling between two layers: drive collection logic processing and drive api. This PR separates that coupling by moving the full item enumeration process into the
API, and letting the collection logic process the
results. This acs as both a simplification of complex code, and a clearer separation of ownership between the two layers.
A detrimental side effect of this change is that drive item enumeration has moved from page-streaming
(ie: each page is fully processed before moving on to the next) and onto batch processing (ie: all items are stored in memory and processed in a single pass). Acknowledging that this is an unacceptable regression, a follow-up PR will appear shortly with better handling for stream-processing enumeration from the API layer as a standard part of the pattern for all pager
implementations.
