add version defaults for Debian, Ubuntu and RedHat (clones)

As discussed before there is an issue with the nginx_version. If the nginx package is not yet installed on a system the fact `nginx_version` is not set. In that case the hard coded default value of `1.16.0` is used. This change will add a default version for some operating systems via hiera data. This avoid the need to run puppet twice to get the correct configuration generated.
