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. Change-Id: Icccf024dc78d82bc453480f3baafb8aaa5c19538 Signed-off-by: JingLu5 <lvjing5@huawei.com>
