This will be useful for adopting dib-lint in other projects, in particular tripleo-image-elements. It allows some dib-lint rules to be used even if the project can't pass all of the checks. The failing checks can then be fixed one at a time and removed from the exclusions list. For consistency, this change reads the new exclusions from tox.ini in the same way as flake8. To use the exclusion mechanism, the the following section can be added to tox.ini: [dib-lint] ignore = sete setu setpipefail Change-Id: I6d8024e7613890e935ceb5e50d0d507bd554d8dd
