ADX-1068 Updated DHIS2 api call for pivot table fetching.

[tomeksabala]

Description

In Cameroon DHIS2 instance is returning 500 error due to the system having >8000 pivot tables.

A workaround would be to minimize the number of pivot tables returned by the query.
I have tried to order the result by lastUpdated date and return last ~200 entries but I couldn’t find a way to order by dates with DHIS2 api.

The only other thing I could came up with was to query pivot tables for either UNAIDS or ONUSIDA (fr). From my experience all countries tag their pivot table with it so I hope the solution will stand.
