  - Merge "Fixing mso-simulator patching"
  - Fixing mso-simulator patching

    Original patch did not work as /etc/hosts file is administrated
    by kubernetes. That msosimulator.sh is also sourced into configMap
    and wrongly transferred back to shell script. This patch is
    providing smarter way for patching /etc/hosts file which is
    still needed.
