Update hiera.yaml to version: 3

This updates the hiera.yaml to version 3. 

The configuration weaves the contributions from ntp at the corresponding site-wide categories (hierarchical level).
Update SuSE.yaml missing end quote

Typo, used ',' instead of '
Update Archlinux.yaml - remove commas
Remove commas from FreeBSD.yaml
Remove commas from Gentoo.yaml
Move lookups back to params.pp

Moving lookups back to params.pp since it is meaningless to have implicit lookups and defaults doing lookups at the same time (the defaults are never triggered). Placing the lookups in params.pp makes it possible to use typed lookups.
Change init.pp to get parameters from params.pp
Remove commas (copy paste error) from params.pp

All lines had trailing commas since they were copied from a parameter list.
Merge pull request #2 from hlindberg/data-in-modules
