Extraction of storage info by type

There was a bug in the node queries. It was assumed that
the returned storage space information was in a particular

This is the haskell implementation of my patch "Extend RPC call

Besides that, this patch moves some types into the Types.hs....

For host names, usually short forms are used, e.g., node1 or node1.sub
