[fuel-master]Install process with Advansed 'Static' method not work

[Aleksey Zvyagintsev]

Master kickstart(dracut\anaconda and bootstrap_admin_node.sh phases ) use wrong nic naming in case real hardware(Dell)
Adminif (mac passed with cmdline ) = eno1

udevadm info --query=property -p /sys/class/net/eno1

    Fix 'adminf' fetching logic

     * Backup ifcfg-* files, not remove
     * Backup ifcfg-* file only if its really needed
     * Check for existing ID_NET_NAME_ONBOARD, ID_NET_NAME_SLOT, ID_NET_NAME_PATH
       (in order) in sys net class, and chose first one.

    In case of real hardware, anaconda can spawn dracut with ID_NET_NAME_ONBOARD
    nic naming. Otherwise, our "Advanced install" logic fetch nic.name by another
    key. Its totally brake "Advanced install" feature

    Closes-bug: #1533652
    Partial-bug: #1533239
