[dnsupdater] Set the record as part of the instance start

Move the DNS configuration to the instance start config, versus a lambda / cloudbridge. This is a bunch simpler, and seems to work to resolve the issue where DNS updates were initermittenly failing.

🙏 to @ZoesDev for the idea to move this to a LaunchTemplate

fixes m-chandler/factorio-spot-pricing#49

Test Plan:
* Started up instance w/o DNS enabled, ensured record was not created,
  checked logs to ensure no updates were attempted
```
