Update git submodules

* Update kubernetes/aai from branch 'master'
  to 5071da297b9e7f58c796bad7d4ae1e3415a039c4
  - Merge "Prepare upgrade to readiness containers v3.0.1"
  - Prepare upgrade to readiness containers v3.0.1

    Readiness 3.x is a new version, not using root user and using stable
    Kubernetes API.
    The upgrade is not doable by just changing version as script path has
    moved.
    Therefore, we must upgrade everything in one shot.
    As AAI is not in the same repo, it's not doable for this component.
    We then change variables only for AAI so we can continue to use older
    images. We'll move AAI just after the rest has been upgraded.
