📄 Description

Describe your changes

Fix the issue with rule squashing, it contained an issue when calculating the total amount of IPs in the Peer map (doesn't include offline peers). That is why squashing did not work.
Also, this commit changes the rules apply behavior. Instead policy:

Apply all rules from the network map
Remove all previously applied rules.
We do:
Apply only new rules
Remove outdated rules

Why the first variant was implemented: when you have a drop policy it is important in which order your rules are and you need a totally clean previous state to apply the new. But in the release, we didn't include a drop policy so we can do this improvement.

Issue ticket number and link

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
