Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Only filter boot_server_from_volume_and_delete via scenario"
  - Only filter boot_server_from_volume_and_delete via scenario

    It can be safely merged as only joid supports '^os-nosdn-lxd-(no)?ha$'
    scenarios. It aims at testing all installers in the same way which
    would have made much sense if another installer supported this
    scenarios.
