Bring kernel optimizations and some other details for ArangoDB benchmark
Even tho is much simpler that our benchmark, there are a few optimizations that caught my attention, specially at:
We need to collect all the kernel optimizations and add them to modules/compute_set/templates/[load|run]/[datanode|client]/cloud-config.yml.tpl
(there are already some tweaks in place, they can be used as examples).
