Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge changes from topics 'allow-pass-ansible-arguments', 'allow-pass-ansible-arguments-force-verify'

    * changes:
      xci: OSA: Fix warning about missing inventory file
      xci: Pass the XCI_PATH variable to all Ansible calls
      xci: Rename XCI_ANSIBLE_VERBOSITY to XCI_ANSIBLE_PARAMS

  - xci: OSA: Fix warning about missing inventory file

    This is similar to 346079ea1b8dbda0c5e282c18f30cbac7e907d1e
    ("xci: Fix warning about missing inventory file")

    This playbook only affects localhost so make it explicit. Fixes:

    [WARNING]: Host file not found: inventory
    [WARNING]: provided hosts list is empty, only localhost is available

  - xci: Pass the XCI_PATH variable to all Ansible calls

    The XCI_PATH variable is used by various playbooks to find the root
    directory of the XCI repository so it's much cleaner to pass it on every
    Ansible call.

  - xci: Rename XCI_ANSIBLE_VERBOSITY to XCI_ANSIBLE_PARAMS

    We don't quite need a specific env variable just for Ansible
    verbosity so we can rename this variable to make it clear that
    it can be used to pass any Ansible option to XCI.
