* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: osa: Fix task status when bootstrapping OpenStack-Ansible"
  - xci: osa: Fix task status when bootstrapping OpenStack-Ansible

    The bootstrap script from the OpenStack-Ansible repository creates
    several things in /opt/ansible-runtime and /usr/local/bin so we can
    check if the final 'openstack-ansible' symlink exists in order to
    report a proper status for that task and even skip if everything
    is prepared already.
