Update to containerd 1.7.18, which now migrated to the errdefs module. The existing errdefs package is now an alias for the module, and should no longer be used directly. This patch: - updates the containerd dependency: https://github.com/containerd/containerd/compare/v1.7.17...v1.7.18 - replaces uses of the old package in favor of the new module - adds a linter check to prevent accidental re-introduction of the old package - adds a linter check to prevent using the "log" package, which was also migrated to a separate module. There are still some uses of the old package in (indirect) dependencies, which should go away over time. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
