Automation wrapper for burst_io

Description:

    This wrapper runs a program that performs burst io activity.
    The program will perform a specified IO for a designated amount
    of time and then sleeps for another amount of time.  Once the program
    wakes up, it will terminate if the overall time of the run has expired,
    else it will perform another IO iteration.
    and does not deal with numa.

Location of underlying workload: part of the github kit

Packages required: gcc,bc,wget

To run:

[root@hawkeye ~]# git clone https://github.com/redhat-performance/io_burst-wrapper
[root@hawkeye ~]# io_burst-wrapper/io_burst/burst_io.sh

The script will set the sizings based on the hardware it is being run.
