Neil 1b98dfe7d1 Implement group password for session auth (#1350) ...

This adds a new `GroupPassword` option to the configuration file. Only
nodes that share the same `GroupPassword` are able to exchange overlay
traffic with each other, allowing the formation of closed networks.

This does not affect peerings, nodes with different `GroupPassword` set
can still forward traffic for each other and act as routers in the wider
network.

If the `GroupPassword` is set, then it is not possible to access public
services or nodes on the public testnet. This is intentional.
