Feature request: wireguard custom tunnel with fqdn as endpoint instad of IP

[christianmerges]

What's the feature 🧐

At the moment a wireguard endpoint can only be an IP address. But this don't works with hosts, who have dynamic ips. Please allow me to use a fqdn instad of ip, so the container can just reconnect after wan ip change by looking up the new ip via dns.

Extra information and references

My only solution is to lookup up the IP manually and recreate the container and restart all containers using the gluetun network.

Please subscribe to #788 since this duplicates it.

PS: I'm slowly working on it, it might be done in 1-3 months
