BUG#: 5485
TITLE: Simplify idle provider detection logic
DESCRIPTION: Move the tracking of the last activity time from the CIMOMHandle to the provider manager.  Remove the unused pending_operation() methods from the CIMOMHandle and provider managers.  Remove the unnecessary CIMOMHandleOpSemaphore class and its uses.  Simplify the Mutex lock requirements in the DefaultProviderManager.  Consolidate the provider unloading logic in the DefaultProviderManager.  Remove the pm_service_op_lock and op_counter classes, consolidating the operation counting in the ProviderOperationCounter class.  Augment the ProviderStatus interface to remove the need for friend relationships
