The IPA ramdisk fails to boot on UEFI compute nodes with iPXE. We see
the following error on the console, followed by a kernel panic:
Fix kernel panic-not syncing: VFS: unable to mount root fs on unknown
block(0,0)
The cause is the lack of an initrd=ironic-agent.initramfs kernel
argument in inspector.ipxe.
The initrd argument is present in the kolla-ansible version of
inspector.ipxe, and now contains all parameters that we need (since
Rocky), so this change simply removes our custom template, and passes
through the extra kernel argument option configuration value.
