[PATCH 2/2][v4] perf/001: a random write buffered fio perf test

[Josef Bacik <josef@toxicpanda.com>]

From: Josef Bacik <jbacik@fb.com>

This uses the new fio results perf helpers to run a rand write buffered
workload on the scratch device.

Signed-off-by: Josef Bacik <jbacik@fb.com>
---
v3->v4:
- use _require_fs_space instead of _scratch_mkfs_sized.
- remove run_check from running fio.

v2->v3:
- use _scratch_mkfs_sized so we skip if our scratch device is too small.
- dump the fio results into teh seqres.full file for debugging.
- fixed the _size math, it was all wrong.

v1->v2:
- no change
