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.
