UEFI bootable ISO image creation fails on recent versions of Ubuntu when partition images are used

[vmud213]

When agent_ilo driver is used to provision the node with partition images in UEFI mode, the ISO image creation fails since isolinux.bin is not found in "/usr/lib/syslinux/". This is observed for higher versions of Ubuntu (>16.04 probably). The isolinux.bin is not part of "syslinux" but part of "isolinux" package for higher versions. Ironic needs to be changed to address the issue.

The location of isolinux.bin can be set with the [DEFAULT]/isolinux_bin config parameter to avoid this error.

I think we can improve documentation and interface validation regarding this issue.

I think we can handle this in a better way. Please look at the updated patch. We should not hardcode the paths in the code. Better to provide them as configuration params.

Ironic no longer supports isolinux/syslinux for booting, and we now use a EFI System Partition image for ISO booting. As such, this item is no longer valid.
