Move build info from management section to status page

[timroes]

As discussed in #11526 we removed the build info and its icon from the management screen, and as @uboness suggested move it to the status page.

Fixes #11526 and fixes #8225

Also closes #8225

I believe this was the only reason the info attribute existed on the management section, so we could clean that up as well. It's referenced in the sections.js and the landing page.

@tylersmalley I've removed it from the section.js. Haven't found it anywhere in the landing page (where it wasn't already removed by the PR beforehand). Are there still some occurrences I've still missed?

[timroes]

Jenkins, test this.

It is a huge improvement to see the build info right there when the status is Red!

[tsullivan]

LGTM. I'm not sure if there is anything that needs to be removed from landing.html, but it doesn't look like it to me.

[cjcenizal]

LGTM!

@timroes, it's in the template here and here. The CSS styles can also be removed.

[timroes]

@tylersmalley I am confused, I already removed these with my first commit here and here. I guess we kind of talked past each other here :-) I will merge this, and if there are still things left over, I would create another PR for it.
