Is 3.5 branch still being supported? If so, I could retarget this PR to 3.5
branch since it is technically a bug fix.
It seems like 3.5-dev is being phased out, so this can probably target
3.6-dev.
> StarGraph shall drop edge properties when dropping edges

> SparkGraphComputer uses StarGraph and StarGraph::StarVertex to represent
> vertices and edges. The StarGraph::StarVertex::dropEdges method drops
> unneeded edges, but it doesn't drop their edge properties, which are stored
> in another data structure (StarGraph::edgeProperties).
> In my use case, I only need edges with a certain label - yet all edge
> properties are loaded and never get dropped. With my local fix, the memory
> footprint used by the Spark program drops by more than 90%.
