diskimage-builder does not run services that it installs, but this is a problem when we lay down the resolv.conf file in puppet with the service not running. So, put in a flag which defaults to true (which is current behavior) that a dib invocation of the puppet can turn off and then dib can plop the file down at the end of the process.
