Regular upgrade path takes just one reboot, but it requires all the processes to be stopped on the node before upgrade might proceed. Under some circumstances and with potential Talos bugs it might not work rendering Talos upgrades almost impossible. Staged upgrades build upon regular install flow to run the upgrade on the node reboot. Such upgrades require two reboots of the node, and it requires two pulls of the installer image, but they should be much less suspicious to the failure. Once the upgrade is staged, node can be rebooted in any possible way, including hard reset and upgrade is performed on the next boot. New ADV format was implemented as well to allow to store install image ref/options across reboots. New format allows for bigger values and takes 50% of the `META` partition. Old ADV is still kept for compatibility reasons. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
