commit f8cd4689e9ba15f91b0b925bcc77adb2c33e0e38
Author: Hervé Beraud <hberaud@redhat.com>
Date:   Tue Jul 21 13:35:14 2020 +0200

    Adding pre-commit
    
    Introduced changes:
    - pre-commit config and rules
    - Add pre-commit to pep8 gate, Flake8 is covered in the pre-commit hooks.
    - Applying fixes for pre-commit compliance in all code.
    
    Also commit hash will be used instead of version tags in pre-commit to
    prevend arbitrary code from running in developer's machines.
    
    pre-commit will be used to:
    - trailing whitespace;
    - Replaces or checks mixed line ending (mixed-line-ending);
    - Forbid files which have a UTF-8 byte-order marker (check-byte-order-marker);
    - Checks that non-binary executables have a proper
      shebang (check-executables-have-shebangs);
    - Check for files that contain merge conflict strings (check-merge-conflict);
    - Check for debugger imports and py37+ breakpoint()
      calls in python source (debug-statements);
    - Attempts to load all yaml files to verify syntax (check-yaml);
    - Run flake8 checks (flake8) (local)
