Add free-form node_data field

[eddyashton]

Resolves #3644.

node_data can be passed at cchost startup time*, or via a set_node_data proposal. The objects returned in /network/nodes also include last_written, as a hint to when each node was added.

* The config argument is a top-level field named node_data_json_file. It's a path to a file for consistency with member_data. We could inline these now that we have a JSON config, rather than requiring them to be dumped to a separate file, but it's a more awkward change when migrating from 1.x to 2.x
