Containerd doesn't support merging plugin configuration from multiple sources, and Talos has several pieces which configure CRI plugin: (see https://github.com/containerd/containerd/issues/5837) * base config * registry mirror config * system extensions * ... So we implement our own simple way of merging config parts (by simply concatenating text files) to build a final `cri.toml`. At the same time containerd migrated to a new format to specify registry mirror configuration, while old way (via CRI config) is going to be removed in 1.7.0. New way also allows to apply most of registry configuration (except for auth) on the fly. Also, containerd was updated to 1.6.0-rc.0 and runc to 1.1.0.
