ASTERIXDB-1005, ASTERIXDB-1263: Clean up subplan flattening:
1. Inline NestedTupleSource and remove SubplanOperator for special cases that
join operators inside the SubplanOperator can be re-targeted for
correlations;
2. Blindly inline NestedTupleSource and remove SubplanOperator for general cases
where the condition of the special case is not met.
