Show Size of Artifacts and Cache

It would be nice if the size of the cache and archived artifacts could be shown at the end of the CI log as well as the number of files (already logged).

I think the only two places where these links are found are anywhere the build is listed in its full row format (the download icon) and in the sidebar of the build screen itself. A size counter for the total artifacts archives and cache in each repo and an overall count in the admin panel would also be extremely helpful. (not applicable to this repo)

Thanks!
