Bug#740096: snapshot.debian.org: please enable HTTPS for https://snapshot.debian.org

[Julien Muchembled]

Control: severity -1 normal

Sorry for my stupid mistake with https://bugs.debian.org/860260
However, the arguments I gave there remain valid, so I allow myself to raise 
the severity of this bug. (I'd even add that I may not have done that mistake 
if it was HTTPS to beginning with.)
