Name of API affected:
Analytics Data Export API

Request summary:
Please include annotations in the export data. 

Use Cases:
We're working on combining GA data (e.g. bounce rate) with web performance metrics (e.g. time to paint, time to interactivity, etc) in a unified UI. Including annotations would be very useful in explaining any sudden changes in performance. 

Note: This is not a duplicate of various other requests to allow write operations (create/update/delete) for annotations. Rather this request is strictly for adding read-only support to access annotation data in the GA Data Export API in particular. 

Thank you.
