[AETHER-1104] Calculate PiPipeconf fingerprint in a deterministic way

New master after taking over a switch was pushing again the pipeline
and all the flows and groups. This was happening because DefaultPiPipeconf
fingerprint was not calculated in a deterministic way across the cluster.

This patch introduces the following changes:
- Implements toString method in each abstraction representing a pipeline
- Hashes the p4Info file to generate a consistent hash of the pipeline model
- Uses a sorted collection to generate a consistent hash of the extensions
