Missing Aggregation PiplineOperator "graphLookup"

[robert.w...@web.de]

Since MongoDB 3.4 there is a "graphLookup" operator for the AggregationPipline.

Could not find any support in ReactiveMongo so far and I also could not find any issue on this.

Is there anything planned soon ?

If not I would like to contribute this PiplineOperator (cannot be done from outside since the PipelineOperator is a sealed trait) in reactivemongo.api.commands.AggregationFramework like the already existing Lookup-PiplineOperator.

Cheers, Rob.
