Add support for SuSE and initd/systemd selection

[michaelsstuff]

Added supoprt for openSuse (leap and thumbleweed 42.x)
removed a lot of exec for the download and tar, to follow best practice and not use exec, but archive
Added if clause in params to query for os and version, to select init or systemd; not perfect but works for the defined systems.

Dunno how I missed this -- is this still good?

[michaelsstuff]

Yes and no. It should work, but I found a few minutes or mistakes I need to fix. I will try to work on it this week

[StrangeWill]

No rush, just let me know, and thanks. 👍

c272bc1 is tested on openSuse 42 and CentOS 7.3
I wanted to rewrite the params to data-in-module style (like the ntp module, with hiera in the module), but that would take some time. It would make adding new OS to the modukle quiete easy. What do you think?

[StrangeWill]

I've never done data-in-module style I don't think, I've always wired my stuff up in roles generally... but I've always wanted to spend the time to go back and add native hiera support.

Feel free to tell me you're done here if you're not needing it badly enough to implement it yourself and I'll look into what that'll take on my end.

Let's close this pull, as it works on suse.
Hiera and data-in-module is nice but definitely for another pull ;-)
