[PATCH V6 15/17] examples/pipeline: rework the link CLI command

[Cristian Dumitrescu <cristian.dumitrescu@intel.com>]

Rework the link CLI command for better alignment with the naming
conventions used in the pipeline I/O specification file. Use the
library linked list of devices and remove the application list.
