  - Merge "Simplify odl scenarios"
  - Simplify odl scenarios

    So far we were building the repo url variable in the odl scenarios. Moving
    that logic to ODL role probably makes more sense as it can be reused by all
    scenarios.

    This patch passes the odl_version to OSA. That variable will be processed by
    the ODL role, which will finally generate the repo url variable
