Stop ignoring E123 and E125 pycodestyle rules

Remove options from flake8 section in tox.ini

This change is one in the series of changes to
align os-brick with Cinder rules.

- E123 'closing bracket does not match indentation of
        opening bracket’s line'
  This option is ignored by default as it is not PEP8 enforced

- E125 'continuation line with same indent as next logical line'

See following for more information:
