[Request] Add entity protection

[Cazok]

Affected Plugin

• Affected Plugin Name: Factions
• Affected Plugin Version: 3.3.2

Describe your Environment

• Server Version: git-Paper-"8b47131da" (MC: 1.16.5)

Current Situation

Entities in factions can be interacted with by people in other factions. Relation status doesn't matter and there isn't a flag or perm option to change it. So, whether it be shearing, leashing, trading, moving/pushing, or even killing entities in other factions, it's all possible currently.

Proposed Changes

Either with a perm option or config setting, add entity protection so people can't do things like go into your faction and slaughter all your villagers or animals in your farm.

Reasons for Changes

As stated above, currently people can steal or slaughter any mob in your faction, which is very frustrating. Adding entity protection is just like having block protection, which currently exists in the plugin, so it's not an uncharacteristic change or anything.
