9ba37402cf Report/render both image and container labels 
Daemon labels will have to wait since the go client (Docker API v1.14) doesn't support
them yet (daemon labels were exposed in Docker API v1.16)

See https://godoc.org/github.com/fsouza/go-dockerclient#Client.Info for details.

3dd59c8b9b 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NodeMetadata is no longer valid.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.
