Have standalone proxy retest their NAT assignment every 24 hours

The webextension will retest their NAT type every 24 hours. We originally didn't have the standalone proxy do this because of an assumption that they will be less mobile than the web-based proxies. However, after an issue with our NAT probe service we've seen our capacity of unrestricted proxies drop and not fully recover. This might be due to several unrestricted proxies failing their NAT check and are unable to recover. See the drop in "nat-unrestricted" snowflakes from the metrics:
