Introduce a runtime parameter for lazy result max cache size

[RobinTF]

Introduce a runtime parameter to control up until which memory size lazy results will tried to be cached.
Making this larger increases runtime and memory overhead, because each lazy result in an execution tree has to be copied until it is larger than the parameter.

Overall this looks very nice,
A few minor comments, and we will play around with this on larger knowledge graphs, to see the effects.
