Spencer Smith 12bfd8dd94 feat: allow for persistence of config data
This PR will allow users to set the `persist: true` value in their
config data to tell talos not to re-pull the config data at each reboot.
The default will still remain as a "pull every time" methodolgy in order
to encourage immutability by default.
