Add fio to regression testing

fio - is a Flexible I/O tester [1]. Fio was originally written to test a
specific workload, either for performance reasons or to find/reproduce a
bug. It allows to test many possible workloads, see examples [2] and
recommended configurations to test latency and throughput, see [3] and
[4]. This patch adds wrapper to pytest around fio and a signle simple
configuration. Other configurations are coming.
