Subject: Improvement: support more parameters in fio testcase

JIRA: YARDSTICK-750

The parameters that fio testcase support now maybe insufficient in some usecase.
The test case should support parameters such as: rwmixwrite, size, direct and numjobs.
This work is about add more parameters that can be specified in options section
in the YAML file.
