Comment (by spacedmonkey):

 I would recommend the following.

 - Add a new upgrade rest endpoint to core.
 - Add a jQueryUI Progress bar to this page.
 - Use the sites end point to get a list of sites on network, paginated.
 - Go through each site on network, one by one, making ajax calls to each
 site's upgrade endpoint.

 There will be performance issues with this on larger network, but it is a
 solvable problem.
