While looking into a build issue, I found that I wanted to see the buildroots for a given repo. While this can be determined from the data, the ui don't provide the option.

I think this should just be a matter of adding another option to query_buildroots(), and providing access to that a few places in the ui.

We do have the repo_references() function on the hub that does this query, but it isn't exported and I think it is probably better to extend query_buildroots().

In the api, we'd probably want this list on the repoinfo page. I'm not sure if there's a place in the cli where it fits (though perhaps the cli should provide the equivalent of the repoinfo page).

Low priority, just a thought.
