Deprecate this module in favour of foreman/puppet

Hi!,

I would like to deprecate this module in favour of https://github.com/theforeman/puppet-puppet The foreman team puts so much effort into their modules. Their amount of unit and acceptance tests is so high. Also upgrades between versions are tested and supported. @voxpupuli/collaborators let me know what you all think about it.
