Adds esi node network show command

The output is a bit ugly; esi node network list essentially breaks up the node port information into multiple columns, but we can't do that for a show command if we want to keep the single attribute/value pair that other OpenStack show command use. Instead, I just dump all the port information into a dict, which looks gross when using the default output, but is fine if you specify json output.

What if we did this?

Suggested change

	node_ports,
	node_ports if parsed_args.formatter == "json" else json.dumps(node_ports, indent=2),

That gets us:

Oh, I like this a lot - good idea!

[tzumainn]

I'll probably make it a bit more exclusionary, since I don't think we want this formatting for, say, csv output.

I've made the suggested changes - let me know what you think!
