Incorporate data on build enviroment performance.

Control for differing build machine specs in CI/teams by including some data on machine performance in generated CSV data. Incorporate a sample usage into R analysis script.

We could generalize this issue a bit. I'd like to collect some other factors that could influence the build time, for example the started task and possibly the parameters it's started with. Using -a --configure-on-demand --parallel --parallel-threads 8 helped me in some cases. JVM flags, whether a daemon is active and JVM flags might also be interesting.

Could this work as a meta line in CSV?

Yes, good to collect as many features as we think are relevant. Add them on as columns.
