The `state-version` module will now initialize the `stateVersion` from
the currently set version.
This makes migrating to the `state-version` module seamless.
This adds a clanModule that will initialize the `system.stateVersion`
upon deploying the machine for the first time.
If the machine is completely reinstalled, then the state version might be
regenerated. But care should be taken if rebuilding from backups.
