[ONOS-6554] Implement BMv2-JSON-to-PiPipelineModel parser

1. Create new module incubator/bmv2/model
2. Move all bmv2 model files to incubator/bmv2/model
3. Using PI core interfaces for all bmv2 models
4. Refactor original bmv2 config parser (Bmv2PipelineModelParser)
5. Refactor original bmv2 config parser test
