Comment 1 for bug 1619074

Sounds reasonable, although I'd like to check the impact of disabling the metadata server - AFAIK there are actually two sets of metadata served via the magic metadata IP, the ec2 stuff and the native key/value pairs, the latter we may want to keep because we expose the sever metadata property in t-h-t (and it can be updated).

Regardless, the occ optimization seems worthwhile
