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.

This implements `docker push` under containerd image store. When
pushing manifest lists that reference a content which is not present in
the local content store, it will attempt to perform the cross-repo mount
the content if possible.
Considering this scenario:
```bash
$ docker pull docker.io/library/busybox
```
This will download manifest list and only host platform-specific
manifest and blobs.
Note, tagging to a different repository (but still the same registry) and pushing:
```bash
$ docker tag docker.io/library/busybox docker.io/private-repo/mybusybox
$ docker push docker.io/private-repo/mybusybox
```
will result in error, because the neither we nor the target repository
doesn't have the manifests that the busybox manifest list references
(because manifests can't be cross-repo mounted).
If for some reason the manifests and configs for all other platforms
would be present in the content store, but only layer blobs were
missing, then the push would work, because the blobs can be cross-repo
mounted (only if we push to the same registry).
