ansible: add grub.cfg hugepages regexp replace
when building the image in chroot we can't run update-grub of grub-mkconfig because both commands probe for root partitions, which doesn't work in the chroot. Instead we manually regexp replace the kernel boot line in /boot/**/grub*.cfg Change-Id: I31fac2a3db4d1d044f11357b1715119066509676 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
