[BP To 7.1.5/7.2.1 MB-56914 ] SELECT on system:functions_cache in a multi query node cluster yields incomplete results with warnings

1. Set up a cluster with more than 1 query node 
2. Create a function on each query node
3. Query system:functions_cache - 

SELECT * FROM system:functions_cache;

      4. The query will return only those function cache entries on the query node that the query was fired to. And does not return all function cache entries across all query nodes. The query also returns a warning: 

"warnings": [

        {

            "code": 11008,

            "msg": "System datastore : scan on /admin/indexes/functions_cache failed - cause: object not found"

        }
