test: basic p2p resilience

[just-mitch]

Depends on https://github.com/AztecProtocol/aztec-packages/issues/8027

We need to ensure our QoS metrics are met in the following scenarios:

### Scenarios
- [ ] Small number of nodes (e.g., 10-50 nodes)
- [ ] Many nodes joining the network (e.g., 100 nodes joining over 5 minutes)
- [ ] Large number of nodes (e.g., 1000+ nodes)
- [ ] Many nodes leaving the network (e.g., 20% of nodes disconnecting over 5 minutes)
