> The ServiceRecord is written twice, once when the container is initially registered and
again in the Docker provider once the IP has been obtained for the container. These occur
asynchronously, so the more important record (the one with the IP) can be overwritten by the
initial record. Only one record needs to be written, so we can stop writing the initial record
when the Docker provider is being used.
