[PATCH 05/10] xfstest: allow fsstress to use load factor where appropriate

[Dmitry Monakhov <dmonakhov@openvz.org>]

1) Add _scale_fsstress_args function which transform argumets according
   to load factors
2) Let all non deterministic fsstress tests to use scaled arguments

I've able to trigger OOPS on xfs see:https://gist.github.com/dmonakhov/4762653
