># Purpose: Restore the network with dhcp enabled for all interfaces
>#          in case network is broken (test by ping).
># Steps:
>#   1. Try to ping the lab controller, nothing to be done if it works,
>#      otherwise go on for the next steps.
>#   2. Enable dhcp in all /etc/sysconfig/network-scripts/ifcfg-*
>#      files (other than ifcfg-lo).
>#   3. Check whether NetworkManager service is available, restart it
>#      if it's available, otherwise jump to step 6.
>#   4. If the restart succeeds, try ping the lab controller again,
>#   5. If the ping succeeds, jump to step 8.
>#   6. Try to restart the network service, if it succeeds, try ping
>#      the lab controller again.
>#   7. If the ping failed, bail out (we have nothing left to try)
>#   8. Upload some logs.
