Changes ONOS BW profile representation to reflect IETF representation

Desired outcome is for the accepted BWP in ONOS to look like 

{   "id": „DT_downstream_default_bw_profile",   "pir": 1168192,   "pbs": 0,   "cir": 0,   "cbs": 0,   "gir": 0 }

The current format is 

 

{   "id": "Default",   "air": 100000,   "cbs": 30,   "cir": 16000,   "ebs": 30,   "eir": 16000  }

 

Extension to the existing BandwidthProfileCodec needs to be done with the new format. The codec needs capability based on the existing information in the json (and vice/versa) to populate only the correct fields of the BandwidthProfileInformationClass. The Olt app in the OLT Meter Service needs to be modified in the method createMeterBands(line 312) to account for the different format. (PIR = CIR + EIR)
