Sergii Golovatiuk fe2608d00a Poweroff server after 10 tries
Some faulty iPXE FW cannot load kernel or initrd file causing DoS on
http server (especially when environment has hundreds of faulty nods).
This patch changes the behavior to poweroff the hardware node after 10
unsuccessful retries to get kernel or initrd over http.

Changes the iPXE behavior to retry a total of 10 times with an increasing
backoff time between each retry in order to not create a Denial of Service
situation with the iPXE HTTP server. Should the retries fail, the node will
be powered-off after a warning is displayed on the console for 30 seconds.
