Client API for NetCache server.

It is undesirable to create objects of this class on the heap because they are essentially smart pointers to the implementation objects allocated internally on the heap.

Note: After sending blob data to a NetCache server, this class waits for a confirmation from the server, and the connection cannot be used before this confirmation is read.
