resolved: add option to disable caching (#3592)

System Internals / systemd - Martin Pitt [ubuntu.com] - 24 June 2016 00:54 UTC

In some cases, caching DNS results locally is not desirable, a it makes DNS cache poisoning attacks a tad easier and also allows users on the system to determine whether or not a particular domain got visited by another user. Thus provide a new "Cache" resolved.conf option to disable it.
