docs: (google-cloud) gapic versions acting as first class APIs

[stephenplusplus]

The nav bar on the docs site:

These are all from the packages inside of google-cloud, e.g. v1 is from @google-cloud/datastore (https://googlecloudplatform.github.io/google-cloud-node/#/docs/datastore/1.0.6/v1). We need to find a way to stuff them back inside of their proper parent, so that v1 is nested under the Datastore link.

@stephenplusplus Poke on this (on Monday). I really, really want to get this to disappear. It looks really awful.

Many hours went to this last week, and it's unfortunately quite a lift. I might need to rethink my approach, with some guidance from @callmehiphop.

A quick fix that came to mind would be linking directly to the sub-module's API documentation page. UX takes a hit in this case, because the context of viewing docs in the umbrella mode would be lost.

Let's discuss in the standup on Monday (after we get through the common stuff since we are combining the languages). I would be okay with a stopgap solution considering we only need to get through a month or two. I just want something that does not look embarrassing. :-)
