Description of PR
Fake storm option was added to reduce the flakiness of test runs seen on some platforms due to actual pfc storm not large enough to trigger pfcwd. This is causing some failures on Mellanox platforms after warm reboot.
Type of change
How did you do it?
Created a module scoped 'fake_storm' fixture and set its status to False for Mellanox platforms
How did you verify/test it?
Ran both the tests (test_pfcwd_function.py and test_pfcwd_warm_reboot.py) on Mellanox and non Mellanox platforms and they passed
Verified in the logs that pfc storm was always generated by the fanout for Mellanox platforms and for non Mellanox platforms only the 1st port had the storm generated by the fanout. Rest of the ports were using the fake storm
