Change Management Behavoir for Repositories

[fionera]

Currently when I include the class by enabling manage_repo, the epel Repo gets defined even when manage_epel is set to false. This collides with the following: https://forge.puppet.com/modules/puppet/epel

Currently params like manage_epel always manage the repository resource and manage_* enable or disable the repo. Rework to manage the resources and NOT to enable/disable repos.

@fionera if you like you can test branch fix/manage-repos-6

I currently have it set to my fork but since you took the same approach it should be fine :) Thank you

Ok, of course I did more. Especially the same for the other supported plattforms.

I will perform acceptence tests and build a release tomorrow or maybe later today.
