Use AddNode when adding nodes to the topology, such that the get merged with any existing node that might be there.

Use an exec'd conntrack in 'events' mode instead of repeatedly execing it for NAT mappings. Also use conntrack to populate the endpoint table.

Fixes to NodeMetadata
...
NewNodeMetadata -> MakeNodeMetadata. It doesn't return a pointer, so
Make is more idiomatic.
Invoke MakeNodeMetadata when necessary. The zero value for a
NodeMetadata is no longer valid.
Split MakeNodeMetadata to two constructors. MakeNodeMetadata when you
don't have anything to prepopulate; MakeNodeMetadataWith when you do.
Also, a fix to the tests in app. We unmarshal a RenderableNode struct,
which has a JSON-ignored NodeMetadata field. The zero value is invalid,
so we need to fix that before performing comparisons.
