Benchmarking datalog transactions using runtime-benchmarks & node-bench

[dergudzon]

Hello. I benchmarked transfer_keep_alive transactions on clear substrate using this tutorial: https://www.shawntabrizi.com/substrate-graph-benchmarks/docs/#/
Now I want to benchmark datalog transactions on robonomics using the same tutorial, but I can't do it because there is no implemented node-bench and runtime-benchmarks in actual robonomics release.

In short, to conduct these tests, I need the robonomics source code with the following capabilities:

• build robonomics binary with the runtime-benchmarks function, with the ability to test datalog transactions
• build node-bench binary, with the ability to test datalog transactions
