Deprecate contributor_aggregate_ytd sort option for Schedule A endpoint (reminder July 20)

[lbeaufort]

It looks like almost no one is sorting by contributor_aggregate_ytd (I see exactly one call in 3 months). We could consider deprecating that in the future to make Schedule A index management easier going forward.

• Begin deprecation process (https://github.com/fecgov/openFEC/wiki/Deprecation-policy)
• Email sent June 19th to two users
• Put in a PR to update documentation. Add deprecation notice to Schedule A for 'contributor_aggregate_ytd' #4423
• PI 12 Innovation sprint: Send reminder email around July 19: Look for any new users of the soon-to-be deprecated functionality
• Sprint 13.1: Remove the sort option (removed 8/11/2020)
• Open up follow up ticket (if needed) for front-end removing that sort (unused)

Hello API user,

This email provides information about changes to the Federal Election Commission’s (FEC) API, openFEC. We are contacting you because an API key associated with your email address used the ‘contributor_aggregate_ytd’ sort option for the ‘/schedules/schedule_a/’ endpoint sometime during the past three months. On August 18, 2020, the FEC will remove this sort option. The remaining sort options for ‘/schedules/schedule_a/’ will be ‘contribution_receipt_date’ and ‘contribution_receipt_amount’.

Should you have any questions, please contact APIinfo@fec.gov.
