Brian Mountford 2c9567e183 Remove old DNS queue processing code.
The old DNS processing was performed by WriteDnsAction, which was invoked by the standard cron fanout action. The new code, which has been running for several months in production, uses ReadDnsQueueAction to do a custom fanout to PublishDnsUpdatesAction. We no longer need the old code, so it's time to remove it.
