[PATCH v3 0/4] benchmark util

[Vladimir Sementsov-Ogievskiy]

Hi all!

v3:
  move all to scripts/simplebench
  add myself as a maintainer of this thing

Here is simple benchmarking utility, to generate performance
comparison tables, like the following:

----------  -------------  -------------  -------------
            backup-1       backup-2       mirror
ssd -> ssd  0.43 +- 0.00   4.48 +- 0.06   4.38 +- 0.02
ssd -> hdd  10.60 +- 0.08  10.69 +- 0.18  10.57 +- 0.05
ssd -> nbd  33.81 +- 0.37  10.67 +- 0.17  10.07 +- 0.07
----------  -------------  -------------  -------------

I'll use this benchmark in other series, hope someone
will like it.
