examples/ip_pipeline: rework flow classification pipeline

Flow classification pipeline implementation is split to two files.
pipeline_flow_classification.c file handles front-end functions (cli
commands parsing) pipeline_flow_classification_ops.c contains
implementation of functions done by pipeline (back-end).
