Host Talos mounts machined socket for API access into the installer container (for upgrades). Installer runs any check it might need to verify compatibility. At the moment following checks are implemented: * Talos version (whether upgrade from version X to Y is supported) * Kubernetes version (whether Kubernetes version X is supported with Talos Y). Fixes #6149 Signed-off-by: Andrey Smirnov <andrey.smirnov@talos-systems.com>
