Fixes issues with Lenovo hardware where the system firmware may display
a blue "Boot Option Restoration" screen after the agent writes an image
to the host in UEFI boot mode, requiring manual intervention before the
deployed node boots. This issue is rooted in multiple changes being made
to the underlying NVRAM configuration of the node. Lenovo engineers
have suggested to *only* change the UEFI NVRAM and not perform
any further changes via the BMC to configure the next boot. Ironic now
does such on Lenovo hardware. More information and background on this
issue can be discovered in
`bug 2053064 <https://bugs.launchpad.net/ironic/+bug/2053064>`_.
