IVGCVSW-3937 Add the necessary components to the ProfilingService class to
process a connection to an external profiling service (e.g. gatord)

 * Added the required components (CommandHandlerRegistry, CommandHandler,
   SendCounterPacket, ...) to the ProfilingService class
 * Reworked the ProfilingService::Run procedure and renamed it to Update
 * Handling all states but Active in the Run method (future work)
 * Updated the unit and tests accordingly
 * Added component tests to check that the Connection Acknowledged packet
   is handled correctly
 * Added test util classes, made the default constructor/destructor protected
   to superclass a ProfilingService object
 * Added IProfilingConnectionFactory interface
