Update git submodules

* Update docs/submodules/multicloud/k8s.git from branch 'master'
  to 047872661b83422149ccf4b46defb5f90f3e7c54
  - Merge "Make aio.sh suitable for CI"
  - Make aio.sh suitable for CI

    aio.sh script currently clones multicloud/k8s repo itself.
    That is unnessary and makes it impossible to hook k8s repository
    to CI system where commit changeset is used to define repository
    files to be tested.

    This commit will remove cloning of multicloud/k8s repository
    and also move aio.sh to baremetal folder which seems to be
    the intended place for it.
