Add Optical ODU cross-connect Intent

Create a new intent: OpticalOduIntent in the OTN Topology.
 - This intent finds a path of OTU links, and
 - Allocates TributarySlots resources on the OTU ports (in the path)
 - also add a utility for converting various SignalTypes to
   OduSignalType, and to build the OduSignalId.

Note: this patch follows the example given in patch
https://gerrit.onosproject.org/#/c/7321 of
separate resource search from resource allocation.
