Fix output for READ operations in kinetibox
Rename kinetibox's source to be more relevant
Update kinetibench

    - Add a connection pool to share between the worker threads.
    It will avoid too much contention on only one connection, and try to make
    the best out of the kinetic driver/simulator.

    - Add the CRUD (Create/Read/Update/Delete) pattern to kinetibench
    instead of simply testing the put throughput.
