PEP 8 fixes

Added  E402 to the ignore errors list.
E402 is "module level import not at top of file"
and ignoring since settings_manager.py needs to modify
the sys.path before importing certain modules.
Since the default ignore list is not used anymore,
rules E121,E123,E126,E226,E24,E704,W503 are now enforced.
Looking at those rules, I believe we should enforce them.
Note E121,E123,E126,E226,E24,E704,W503 are all in the default
ignore list, so if no ignore list is provided in the
setup.cfg these errors are ignored.

from pycodestyle --help

--ignore=errors      skip errors and warnings (e.g. E4,W) (default:
                     E121,E123,E126,E226,E24,E704,W503)
