cp_pooled_thread_client_interface associates an action (thread function) with a cp_pooled_thread_scheduler for clients that require a variable number of threads. This interface holds 3 functions pointers that must be supplied by client code:
o report_load - should return a measure of the load for this client's action,
such as the number of open requests the client has to handle
o shrink - will be called by the framework to stop one client thread
o action - the thread function for this client
application code should call the cp_pooled_thread_client_get* functions to instantiate threads, thereby activating the load balancing framework.
cp_pooled_thread_client_negociate should be called by client code on high loads to request additional threads from the framework.
