Add support for configuring OLT access device data with uplink/vlan information.
This is required when running on target OLT switches where we have to configure
the uplink/vlan information with the device ids for ONOS to program IGMP flows correctly.
Add methods for getting devices and flows from ONOS rest interface.
Change relevant OnosCtrl methods to class methods that are applicable for global onos configurations.
