Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: idf: Add more information for installers and flavors"
  - xci: idf: Add more information for installers and flavors

    Each installer has its own Ansible groups so we need record such
    information separately. Moreover, we need to add 'flavor' information
    to the IDF so we know which hosts belong to what flavor. This also
    fixes the kubernetes installer type to be 'kubespray' instead of 'k8s'
    Finally, we extend the IDF to also set appropriate hostnames for the
    nodes.
