Support FQDN type address

**Is your feature request related to a problem? Please describe.**
In some cases, we want to route/allow access to a destination, of which the IP can change.
One of our current VPN solutions is a firewall vendor ssl vpn, which offers policy based routing and supports address objects of the type FQDN.
It keeps track of the TTL of the address, and in case it changes, it updates the IP's.

**Describe the solution you'd like**
Can defguard support FQDN type addresses in both AllowedIPs and ACL?

**Describe alternatives you've considered**
Route all traffic through defguard, but we prefer to only route relevant/specified traffic
