-A Class representing an O-RAN O-Cloud resource pool for O-RAN distributed units (ORanDu)
-By default all O-RAN-DUs associated with the towers around are deployed here.
-Maybe dedicated hardware is required to host O-DUs, but it is expected
-that the O-Cloud mechanism and concepts can be applied here.
