Feature request: Force IP Update periodically optionally

[killerbigpoint]

1. What's the feature?
   Been using Noip on the free plan for a while now. Now the problem is that after 30 days of "inactivity" without any IP record updates it will auto delete your dns. Have an option to force update every like 7 days or so, so it can keep operating.

2. Extra information?
   Since I use truenas for this, maybe an enviroment option would be nice too but that's up to you
