genfio: Adding exec_{pre|post}run support

It's pretty useful being able to run some commands before or after a
job. That could be use to ask some external storage array to loose its
cache or return in a particular configuration state.

The -A (stands for After) or -B (stands for Before) allow user to define
what commands shall be run before or after a job.
