 When we run a tor 'make test-network-all' we create several chutney
 networks in quick succession. If one of them fails, it's very hard to
 locate its logs.

 So instead of moving the 'nodes' directory to a timestamped backup path
 when the *next* network is created, let's *create* the nodes directory at
 a timestamped path, and then link the latest timestamped directory to
 nodes.

 Then we can log the unchanging path, so users can find the logs later.
