Add scripts to setup development env

Usage:

    apt-get install -y genisoimage \
        libvirt-bin \
        qemu-kvm
    service libvirt-bin restart

    cd bottlenecks/utils/rubbos_dev_env_setup
    ./deploy.sh

The deploy.sh will create 9 vms (ip from 192.168.122.11 ~ 19):
control,httpd,mysql,tomcat,client1,client2,client3,client4,benchmark

TODO: add scripts to build initial disk.img
