> It is currently possible for a component instance to have READY status before 
> the AM retrieves an IP for the container. We should make sure the IP has been 
> retrieved before marking the instance as READY.
> This default probe could also have an option to check for a DNS entry for the 
> instance's hostname if a DNS address is provided.
