random precondition fio job timeout with 1800s when run case fio_fb.py with config fio_fb_perf.json

[kwzhu123]

1.run test case fio_fb.py with config fio_fb_perf.json
2.when run to step random precondition, got assert : random precondition timed out. Failed to complete within 1800 seconds on x.x.x.x
3.in ocp-diag-autoval-ssd/src/autoval_ssd/lib/utils/fio_runner.py def create_fio_job, will set fio timeout:
if key == "RUNTIME":
self.fio_timeout = DiskUtils.get_seconds(value) + 600

and fio_fb_perf.json set random pattern run time to "RUNTIME": "1200s", this worked for patten test, but seq/random precondition used this fio timeout value too, if seq/random 1 loops used more than 1200+600=1800s, case will failed, need enhancement it.
