Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: roles: configure-network: Wait for connection when configuring the network"
  - xci: roles: configure-network: Wait for connection when configuring the network

    Ansible some times loses connection with the host after we configure its
    network interface. This shouldn't happen since the host is actually up
    and running. As a result of which, we need to fire-and-forget the
    restart of the network service and then try to reach the SSH port. We
    also need to make sure that all required packages are installed.
    Finally, we drop the 'ignore_errors' parameter since we really need to
    know when the networking configuration has failed.
