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
