"""Test various net timeouts.
- Create three bitcoind nodes:
no_verack_node - we never send a verack in response to their version
no_version_node - we never send a version (only a ping)
no_send_node - we never send any P2P message.
- Start all three nodes
- Wait 1 second
- Assert that we're connected
- Send a ping to no_verack_node and no_version_node
- Wait 30 seconds
- Assert that we're still connected
- Send a ping to no_verack_node and no_version_node
- Wait 31 seconds
- Assert that we're no longer connected (timeout to receive version/verack is 60 seconds)
