When images are pulled by Talos or via CRI plugin, configuration for each registry is applied. Mirrors allow to redirect pull request to either local registry or cached registry. Auth & TLS enable authentication and TLS authentication for non-public registries. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
