Install wrk on the benchmark machine

[joyeecheung]

Hi, it appears that the benchmark machine does not have wrk or autocannon installed so right now it does not produce meaningful results on the HTTP benchmarks (See: nodejs/node#16557). I have seen #821 (comment) but have not figured out how/where to update the ansible scripts for the benchmark CI machine, I guess alternatively one would need to ssh to that server and manually install the dependencies? Right now I would prefer using wrk over autocannon, so the things needs to be done are basically equivalent to:

apt-get install wrk

Let me know if there are things that I can help with.

ping -- has this been done?

[maclover7]

Ref #868, looks like no Ansible playbook yet for benchmark machines. I am more than happy to help mentor and get this done if that helps at all, I've been doing a lot recently with the Ansible scripts :)

@maclover7 it would be great if you could help get the ansible scripts created.

In the end I manually added wrk so closing this issue.
