Synchronize with DHIS2 only the Geo-Objects that have changed since the last synchronization #901

User stories

Request by @viengthong2015 from the Center for Health Statistics and Information, Laos As a Registry Administrator, I want to be able to synchronize only the Geo-Objects that have changed since the last synchronization. Currently, GeoPrism Registry synchronizes all Geo-Objects of a given type as specified in the DHIS2 synchronization configuration. This will make it easier to identify which organization units have been updated by GeoPrism Registry based on the update date.

Problems this relates to

External system synchronization

Proposed solution

Whenever running a synchronization with an external system, GeoPrism Registry checks which changes were synchronized in a previous run, and compares all the Geo-Objects and their attributes about to be synchronized. It then generates a 'changeset' to be synchronized.

Considered alternatives

Option to synchronize specific Geo-Objects by specifying their codes.

Additional context

None

This could potentially be implemented by having GeoPrism Registry first checking if the attributes of the corresponding organization unit are the same as the Geo-Object, and if there is any difference, only then updating the organization unit.
