[ONOS-4588] Separate optical driver from "default" driver bundle

Note: If you're using optical devices currently in "default" driver bundle,
(LINC-OE, Calient fiber switch, ECI devices, OpLink ROADM)

you'll need to load the driver/app "drivers.optical" in adition to default drivers

e.g.,
a) Add to cell definition
 export ONOS_APPS=${ONOS_APPS},drivers.optical

b) Activate after starting ONOS
 onos> app activate org.onosproject.drivers.optical
