Add page and size parameters to /api/validSources and /api/validDestinations endpoints

Hi everyone,
The Mozambique implementation asked us to add a management screen for Valid Sources. It turned out that endpoint /api/validSources has no page and size parameters that are necessary for this task. The same applies to endpoint /api/validDestinations. As part of our task, we would like to add these two parameters to /api/validSources and /api/validDestinations in OpenLMIS Core.

Let us know if you have any questions or concerns about the above.
If you have no objections, we will start working on adding these parameters next week.

Best regards,
Aleksandra

Nope, no objections - I think we try to keep forward compatibility here by keeping the same return of the full set when those parameters are absent for this reason - no major version change needed.
