Create os-nosdn-osm scenario

The tasks added by this change
- configure opnfv host by installing required OSM packages, configuring
lxd and lxd bridge, making devuser member of lxd and docker groups
- clone OSM devops repo and checks out specific version
- execute install_osm.sh script with certain arguments to ensure script
runs unattended

The installation of OSM is based on
    https://osm.etsi.org/wikipub/index.php/OSM_Release_FOUR#Install_OSM_Release_FOUR
