snabb_bot and cperf: Continuous integration and benchmarking.

This branch includes some shell scripts intended to support the devopment process of Snabb Switch.

`src/scripts/cperf/`: This is a set of scripts for running and comparing benchmarks of different Snabb Switch versions. They can be used to plot the chronological changes in benchmarking results as a graph rendering as well as to compare benchmark results of arbitrary commits.

`src/scripts/snabb_bot/`: These scripts implement a rudimentary no-cloud version of Travis-CI, they can be used to run tests and benchmarks for new/updated pull requests on our lab servers. The results will be posted to GitHub in form of *commit statuses*.
