[ndnSIM] How to choose the nearest server with App Instances

[Alex Afanasyev]

Hi Xiaoke,

I feel that in NDN, choice of a specific producer **should not** be consumer's task.  It should NDN network job (e.g., forwarding strategy's job on a node) to figure out (based on signals from the consumers) that interest should be forwarded somewhere else.   At the same time, consumer will just request data by name, without caring what is happening behind the scenes.
