Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "vping&snaps_xxx support not_hugepage_supported pod"
  - vping&snaps_xxx support not_hugepage_supported pod

    if flavor_metadata is set to {'hw:mem_page_size': 'any'}, it means
    hugepage must be support by pod. but actually hugepage is not supported
    by all pods
