Flow decomposer support for Tech Profile Reference in metadata instead of using Flow Table ID as reference in Table 1.
Also in this patch:
- Update flow count field of meter stats
- ONU root field was True and because of this flow decomposer was not working properly - it is fixed (now onu root field is false) - related to VOL-1354
- Meter & write metadata support is added to vcli
- No-action (drop) flow support is added.
- Removed broken wildcard inport support and in-band control support
- Meter functions (meter stats reply, meter modify etc.) are fixed
- Metadata information passed on to the OLT and ONU Adapters.
- Meter Reference in all Flow Tables passed on to the OLT and ONU Adapters.
- Fixed unit tests and added more unit tests
- Fixed ponsim (partially) to deal with changes to flow decomposer
