Base class used for MCpr activities that need to issue authorisation requests to the NetUps.

Derives from MPolicyCheckRequestOriginator to receive NetUps callbacks when request has completed.

Contains Mesh Machine methods for interacting with the NetUps and also contains "node specific" virtual methods for retrieving information required by NetUps. These methods are intended to be overridden in the specific node to delineate node specific functions from the remaining MCpr generic functions held in this class:

GetServiceId() - retrieves the UPS ServiceId (a UID). Although the ServiceId is defined in the particular MCpr, a default implementation is provided that returns the TierId from the Access Point Config as the ServiceId.

GetUpsDestinationString() - forms a human readable destination address string. The operation of this function depends on the form of the destination address (e.g. IPv4/IPv6) which, in turn, depends on the MCpr.
