Add tramp/network/latency benchmarking suite (WIP)

A system made up of a fig/docker combination.

Motivation: Many changes here affects slow performance on slow file systems like TRAMP.. We need something to do benchmark regression tests.. 
I have built this prototype using a fig/docker combination, everything is startable through

projectile | runs the test suite
polipo | http proxy to speed up cask rebuilds
remotebench | the projectile contrainer connects to
A shared volume (mount point) should be created that both the projectile and remote bench containers has access to where a bunch of repositories and other things can be added to have a real world like file system that can be accessed either locally from the projectile container or from the remotebench container via ssh.
