Fixes #4815 This implements the following steps: * machine configuration updates * pulling and unpacking system extension images * validating, listing system extensions * re-packing system extensions * preserving installed extensions in `/etc/extensions.yaml` Once extension is enabled, raw information can be queried with: ``` $ talosctl -n 172.20.0.2 cat /etc/extensions.yaml layers: - image: 000.ghcr.io-smira-gvisor-c927b54-dirty.sqsh metadata: name: gvisor version: 20220117.0-v1.0.0 author: Andrew Rynhard description: | This system extension provides gVisor using containerd's runtime handler. compatibility: talos: version: '> v0.15.0-alpha.1' ``` This was tested with the `gvisor` system extension.
