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.

Affected Versions: * 2.2.0 (beta) * 2.1.0
