design a way to benchmark server scalability

as part of activity 1 in the roadmap https://0xacab.org/leap/soledad/wikis/2017-roadmap we referred to expose some live benchmarks for measuring the scalability of the server (to be used, mainly, in activities 4 and 5 of the roadmap).

definition of done

I would consider "done" the discussion and creation of a new issue with the proposed steps for benchmarking the behavior of a server when serving requests to an elevated number of clients.
