Add scaffolding support for new index features

[khellang]

I punted on scaffolding support for #662 and #699. We should look into adding support for this.

@khellang are you interested in doing this in the very near future?

I don't know what I can commit to, as my time is fairly limited in the near future. You guys just happened to ping me at a good time last night 😉

As I mentioned in #662, I tried looking into it, but it was fairly involved to pull the index metadata and I didn't have a database set up to do actual testing.

OK, post a note here if and when you start working on this, I'll do the same - we'll see who gets there first :)

Taking this, feel like doing some scaffolding hacking :)
