Description of problem: Currently Unbound does not provide an option to set the maximum negative cache TTL. This needs to be implemented first, so we can set a low negative cache TTL in Fedora, to prevent user experience issue in the early stages. This is Fedora bug for tracking purposes, due to the Fedora 23 "default DNS resolver" change. Upstream bug: https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=675
