While clearing out the sysv and upstart bits this got inadvertently as well.

The reason it wasn't realized for so long is that:
a) it is a conffile which was not autoremoved on upgrade, so any upgrade continued to work correctly with the old file
b) it is an optional file not needed to be modified for most common use cases, the scripts are hardened against the file being missing so they work

Yet if someone "wants" to use one of the features in those files AND is on a new zesty/artful install the file will be missing.

Fortunately we can add that without too much extra conffile care.
If on a system the file is around already it will be considered as a usual conffile on upgrade (and content didn't change) and if a system never had the file it will deploy its default content.
