feature: option to choose default ACLs

[diegocn]

Hello, this is a feature request for the netbird team.

As a network admin, I’d like to have the option to create an ACL rule and then set it as the default one for all devices within my managed network.

This is different of having the current default ACL that enforces all devices to be peers.

Edit: it would be nice to have the option of choosing multiple “default groups” by default.
