  - Fix cherrypy import failure due to more-itertools

    more-itertools version 6.0.0 is incompatible with python-2.7
    importing cherrypy failes due to this.
    Changed startAnsibleServ.sh to explicitly install 'more-itertools' version 5.0.0
    Also added 'apt-get update' before installing software-properties-common package which failed earlier to install.
    Container starts without problem after these changes
