Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "New SHA for ODL"
  - New SHA for ODL

    We need a patch in the ODL role to be able to deploy a stable ODL.
    Before this patch, it is not possible to deploy with a stable
    version of ODL and we are always deploying with the tip of the branch.
    However, it is useful to deploy with a version which we know for sure
    that it is working.
