    VirtualBox network fixes and the dockerless mode support

    This commit include changes:

     * using the VirtualBox scripts the Fuel master node now always
       booted with kernel option 'wait_for_external_config=yes' to
       provide the same deployment functionality as in the 'fuel-qa'.

     * settings for the kernel command line moved to the top config
       file, because the settings wich could be edited should be placed
       there.

     * because of configuration task moved to the correct place there
       is no need to parse 'bootstrap_admin_node.log' and always follow
       the changes in the 'fuel-library', so all parsing logic removed
       from the scripts. This also simplifies networking changes and
       there is no need to patch the files on the fly and restart
       docker containers if they used.

     * variable 'vm_master_nat_gateway' removed from the 'config.sh'
       and from the 'enable_outbound_network_for_product_vm' because
       gateway should be set from the DHCP lease.

     * the sysconfig configuration files on the fuel master node now
       configured the right way. the backup files for configuration
       files are created. also added some comments for changes in the
       scripts.

     * now the default routing on the fuel master node correctly
       configured without creating the second default route. also
       ZeroConf route creation and NetworkManager now switched off
       to correct work of the network service.

     * the 'resolv.conf', 'dnsmasq.upstream' and 'astute.yaml' now
       correctly modified and could contain up to three DNS nameservers.

     * added support for the new dockerless 9.0 Fuel.

    Implements blueprint: get-rid-docker-containers
