DDNS Multi Updater

ddnsmulti will read dynamic update requests, formatted as YAML, from a queue directory and ensure that all updates are sent to a set of authoritative nameservers. It will optionally keep track of what requests has been accepted to what nameserver and retransit any pending updates.

In addition to the update requests, ddnsmulti will optionally keep an JSON-based index in the queue directory. The index contains all pending transactions and their status.
