If this project includes a feature flag, please complete all upgrade/downgrade testing as part of this ticket.

1. Test how the feature behaves when upgrading FCV turns the feature on
2. Test that the correct behavior occurs when downgrading FCV completely and then upgrading FCV completely
3. Test that the correct feature behavior occurs if the FCV downgrade fails after only reaching the `downgrading` FCV state and then FCV is fully upgraded again
4. Test that anything added by this project to the setFCV command must be idempotent/retryable.
