Improved log path handling

Validations logging now has a documented fallback,
in order to improve readability and provide reference.

Tests are included.

Complementary patch for validations_commons callbacks
is optional, as the behavior should stay largely the same.

Depends-On: https://review.opendev.org/c/openstack/validations-libs/+/794638
