Update annotation-service to latest

[stephen-soltesz]

This change updates m-lab/etl to use the latest version of the annotation-service repo and struct definitions.

This change will update the BQ schemas used by all datatypes to include the new annotation-service Geo and Network fields that match the fields defined by the uuid-annotator. This update is in preparation for the annotation export process after reprocessing all historical data with the new annotation-service fields.

The change to update-schema ensures that all current template tables also receive the updated schemas. Without this change the parser would stall. We could delete these tables, but would lose work-to-date.
