Feat: Upgrading Talos with config files

[patatman]

Feature Request

Managing upgrades trough the configuration files.

Description

With the new v1Alpha2, it might be worth to consider using files as a way to upgrade Talos. More of declarative state, and pulling the config. This is similar to the way you would run kubectl apply -f But with the added option of running it of a metadata-server.

A oversimplified workflow would be:

• Edit config file on metadata-server (webserver)
• PXE (re)boot
• Talos sees install exists, and persist:false
• repulls config from metadata-server
• Checks for diff against config on disk
• If there is a diff, pull new image.
• Install on disk
• Reboot to Disk

I would really love to see a declarative mechanism for upgrading Talos.
