Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "ansible: add grub.cfg hugepages regexp replace"
  - 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
