Log/Enforce repository permissions

[bastelfreak]

The default permissions for our org are read only for repositories. Our collaborators group gets write access to modules. From time to time, this gets misconfigured or people forget about it after a migration to us. This is something that should be logged / fixed on a regular basis (or can we get notifications for it?). If it got changed it would be nice if we could figure out who did it.

GitHub allows us to configure multiple things in a repository:

• https://developer.github.com/v3/repos/#update-a-repository

Besides the permissions, there are some other things we need to do:

• homepage => https://forge.puppet.com/$forgeuser/modulename
• has_issues => true
• has_projects => true
• has_wiki => true
• default_branch => 'master'
• allow_squash_merge => true
• allow_merge_commit => true
• allow_rebase_merge => true
• delete_branch_on_merge => true

where the last option,delete_branch_on_merge, is the most important one. It's currently false on most repos but should be true.
