Merge netsim mig to master (#17241)
* swarm: merged stream-tests migration to develop * swarm/network: expose simulation RandomUpNode to use in stream tests * swarm/network: wait for subs in PeerEvents and fix stream.runSyncTest * swarm: enforce waitkademlia for snapshot tests * swarm: fixed syncer tests and snapshot_sync_test * swarm: linting of simulation package * swarm: address review comments * swarm/network/stream: fix delivery_test bugs and refactor * swarm/network/stream: addressed PR comments @janos * swarm/network/stream: enforce waitKademlia, improve TestIntervals * swarm/network/stream: TestIntervals not waiting for chunk to be stored
