New network concept, peers seem to try to connect to themselves

[Gauss23]

Describe the problem

When trying to migrate from Network Routes to Networks, I see that the nodes involved are trying to connect to themselves as loopback

To Reproduce

Steps to reproduce the behavior:

1. Go to 'Networks'
2. Create a new network
3. Create a CIDR resource
4. add a policy, where the source is a peer or a group of peers (not including the routing peer) and the destination is just an empty group
5. check the connected peers, the routing peer will have itself as a peer it wants to connect to

Expected behavior

Peers should not do loopback to themself
