Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "armband-deploy: rm translation of virtual POD name"
  - armband-deploy: rm translation of virtual POD name

    Old Fuel deploy scripts required the virtual POD name to be
    virtual_kvm, which needed to be translated at CI level after
    source enviroment specific configuration.

    New Fuel deploy scripts no longer need this translation, so
    drop it.
