Report additional Node info

[josecoll]

Would be great if this utility could also report details of:

• Database (version, driver)
• Message Broker (version, driver)

Give me links to the parts of the RPC API and I'll add them. Perhaps I'll start add some further parameters about exactly what data is returned.

The other obvious item I forgot to mention was "CorDapps" (deployed to the Node, and their associated version and flows).
