[VOL-1703]:
While adding flow for a device, adapter makes sync call to core to fetch
the OLT device structure. The NNI Intf ID was then fetched from the OLT
device structure.
This sync call during flow processing takes more seconds (2-3~ secs),
but core has default timeout 500ms and used to timeout. On failure it
used to re-initiate the whole procedure again. This was going on in an
endless loop.
To fix this problem, the NNI Intf ID is cached locally in the adapter,
and there is no query initiated to Core.
