Fixed PEP 8 style using autopep8

Used autopep8 to correct styling.
Ran autopep8 on openbmc-test-automation, autopep8 is not
able to fix all styling issues. There is still around
1000 styling violations in openbmc-test-automation.
More information on autopep8 can be found here,
https://pypi.python.org/pypi/autopep8
