Update portmapping with switching-pool from notif

Update portmapping with switching-pool from notif

Update the switching-pool-lcp list of portmapping from a
change-notification received from a 7.1 muxponder device. Manage such a
7.1 device notification to create, or update if object already exists,
the switching-pool-lcp container abstracting the device
odu-switching-pools one.
- add new updatePortMappingWithOduSwitchingPools method in PortMapping
interface
- implement this method in PortMappingImpl and PortMappingVersion710
classes
- keep the existing building of switching-pool-lcp in
createXpdrPortMapping method in case existing odu-switching-pools would
exist at the initial device connection
- manage reception of device notification whose target is
odu-switching-pools and port-list in DeviceListener710 class
