server will not boot from pxe if it does not support command 'chassis bootdev pxe ' with 'persistent' option

[Haomeng,Wang]

I tested our pxe_ipmitool driver, found an issue, if the server ipmi does not support the command 'chassis bootdev pxe options=persistent' with 'persistent' option', that mean the boot order will not be stored for 2nd time, it just effect for the first time, it just restart from 'old' boot device, if it is not pxe, server will hang, because local hd has no boot loader for our pxe_ipmitool driver.

So two solutions:

1. Add the feature to create boot loader for pxe driver
2. Call 'chassis bootdev pxe' for each time before power on the server to make sure booting from pxe

I think both options should be eventually implemented, and this bug is more about the second option.

    When boot option is not persisted, set boot on next power on

    If the server ipmi does not support the command 'chassis bootdev'
    with 'persistent' option', the boot device cannot be set persistently
    and will not be set for the 2nd boot. This change proposes to add
    a new parameter in node's driver_info to force set the boot device for
    each power on.
