        4. Run network checker
        5. Migrate Fuel Master to the compute node
        6. Check that containers are up and running on the Fuel Master

    Fix allows fuel-migrate script work under centos-7.

       Was made:

     1 Removed hacks for System-V functionality. Instead was added stub
     emulating job performing in umm mode. It allow in future use UMM package
     and don't keep in mind os used on host.
     2 Docker storage clone procedure was changed.
     3 Grub installation procedure was changed
     4 Add possibility generate udev-net-rules
