WIP: data/Debian.yaml, add package- and service-names for Debian-based prometheus-packages

[unki]

Together with #430 this PR adapts the Debian-defaults regarding package- and service-names like they are actually present in Debian. e.g. all exporters are prefixed with prometheus-.

@unki can you take a look at the failing tests?

Need your advice here.

The situation is - even before my #430 - that a lot of exporters are using $service_name for things like naming the installation-directory. e.g. see redis_exporter.pp:L107.

When the $service_names for Debian are now referring their actual service-names on Debian - a init.d or systemd.service, like e.g. prometheus-redis-exporter - all the tests here are failing because they have the ordinary exporter-names like redis_exporter hardcoded.

Shall I...

• ... change the exporters to use $package_name instead of $service_name and pin the tests to the upstream exporter-names (redis_exporter)?
• ... change the tests to test a package-based installation on Debian instead of the download-url variant?

i think that would be the way to go. if i remember correctly, that's how Arch does it.

and thanks for tackling this! i've got profiles here to work around this problem, would be great to get rid of them.

In general I think we should always rely on packages if some are available. Arch Linux packages a few exporters and I implemented that in this module as well.
