Support passthrough of override_path field for containerd mirrors

[backjo]

What I'd like:
ContainerD allows specifying the override_path field for mirrors that do not have a '/v2' path after the provided endpoint. This would be useful for folks using JFrog Artifactory or Harbor as a mirror, as these do not fully support this v2 path. https://github.com/containerd/containerd/blob/main/docs/hosts.md#override_path-field
Any alternatives you've considered:

Hi @backjo , thanks for creating the issue. We'll look into supporting this as a Bottlerocket setting.

Sorry for the milestone spam, we were deliberating scope for our release schedule. This depends on us moving away from inline registry mirror configuration per #1963.
