    I was wrong about the debug dump file. It is not a process dump. It seems to be used only
in alloc_pool.c
    
    This is a file to which debug information is written when the logger has not yet started
or has already been shutdown. When the loggers are not available, the router writes to this
file.

> Right now all router statistics attributes like deliveriesIngress, rejectedDeliveries,
droppedPresettledDeliveries etc. reside in the router entity..
>  
> Router Config Attributes  like saslConfigPath, saslConfigName, helloIntervalSeconds,
helloMaxAgeSeconds etc. also reside in the router entity
>  
> When a qdmanage query is issued, the results do not include the router config attributes.
This is because the core does not have access to these attributes

> The solution to this problem is to create a new entity called RouterStats and move all
the statistics related attributes to RouterStats. This RouterStats entity will be handled
by the C management agent.
>  
> The old Router entity which is currently handled by the C agent will be handled by the
Python agent instead.
