What type of re_data dbt macro you would like to add

• validate

What macro should be doing

Return true is string is a valid JSON and can be parsed to JSON

Currently EntityResourceTest#get_entityListWithPagination_200 pagination creates 40 entities and performs listing with pagination tests. This is done for all the entities from the base class. such as table, databases, dashboards etc.

    int maxEntities = 40;

Change maxEntities to a random number between 5 - 40 to reduce the time spent in testing during builds.
