Prior to this Werk it was possible for a user to read a hosts configuration
(using GET on /objects/host_config/<host_name>) even if that user was not
in the contact group of that host.
The REST-API will correctly check a users permissions before serving a response in that case and report a 403 error if the user cannot access the host's config.
