Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "jjb: xci: xci-set-scenario: Allow automatic detection of generic scenarios"
  - jjb: xci: xci-set-scenario: Allow automatic detection of generic scenarios

    The list of supported scenarios is hardcoded and this makes it difficult
    to test new scenarios. As such, lets determine the scenario and the
    installer based on the actual files that have been changed on every
    patchset.
