## 2025-04-24 ACL alias types

We decided to introduce two ACL alias types to explicitly define how to handle them when generating firewall rules:

* Destination aliases - define a complete destination (like an ACL itself) and are translated into a dedicated set of firewall rules; in effect those work like pre-defined destinations
* Component aliases - define a part of a destination (IPs, ports, protocols or any combination of those) and are combined with the inputs configured manually for an ACL - IPs are added to ACL IPs etc.
