Update git submodules

Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "Set VM node names and log the installer version based on installer"
  - Set VM node names and log the installer version based on installer

    The VM nodes are named using OpenStack terminology but since we
    now have Kubernetes scenario, it is appropriate to name the nodes
    accordingly.

    Apart from that, we normally log the version of OSA which is not
    correct for kubernetes deployments. Logging Kubespray version would
    be correct for this scenario.
