Description
Exacerbated by DRILL-2732, if a project exists between the scan and the filter, the current Mongo pushdown filter rule will not push the filter down into the scan.
As implemented in DRILL-1950 and for the partition prune optimizer rule, the pushdown filter should handle the above scenario (by implementing the rule for both "filter/scan" and "filter/project/scan" scenarios).
