Query Optimization
Before SERVER-45620 we would allow a nested pipeline with an illegal stage. For example, $facet is not allowed in a $facet. However, we would allow $facet inside a $lookup inside a $facet. This is no longer allowed, but the error message is misleading – in the above example we would report "$lookup is not allowed in $facet". We should look into making the correct information available, or making the error message more generic.
