Merge lp:~asac/ubuntu-test-cases/use-top-and-always-dumb-toplog into lp:ubuntu-test-cases

[Alexander Sack]

+ use top in batchmode instead of vmstat
+ improve logging; echo cli arguments given as well as
+ dumb top_log regardless of success and failyure
+ top_log is now more useful to see what was going on as we dumb exactly what was measured

[lp:~asac/ubuntu-test-cases/use-top-and-always-dumb-toplog]

14. By Alexander Sack on 2013-08-19

fix idle_avg calc to deal better with non-natural numbers getting passed

15. By Alexander Sack on 2013-08-19

improve systemsettle idle measurement run logging now that we don't run vmstat anymore

16. By Alexander Sack on 2013-08-19

since we now use top instead of vmstat, let's use s/vmstat/top/ for all variables as well

17. By Alexander Sack on 2013-08-19

don't log the top command used in systemsettle anymore
