Use openstack library oslo_config for parsing configuration options
from the command line and configuration files.
Refer http://docs.openstack.org/developer/oslo.config/ or rally
source code for more info on oslo_config library usage.

This patch is initially for test result dispatcher configuration,
but it is very general to use.

  0) install yardstick
  1) mkdir /etc/yardstick
  2) cp <repo_root_dir>/etc/yardstick/yardstick.conf.sample \
        /etc/yardstick/yardstick.conf
  3) edit /etc/yardstick/yardstick.conf
  4) run `yardstick task start xxx` cmd
