Bug#803713: Elasticsearch should not be part of a Debian release

Not necessarily. It should just not become part of stretch because there
is no sensible way to support it.

BTW: Apparently I was wrong about the 1.7.x branch no longer being
supported by the upstream project: A tag for v1.7.6 recently appeared in
the Github repo a few days ago. Their policy about security issues is
still Oracle-grade stupid and user-hostile.
