    Fix pylint zuul failure

    The starlingx-staging repo was incorrectly being pointed at for tox
    pylint dependencies. The dependencies were colliding with
    dependencies from other repos.

    That repo is not used anymore, instead the latest stable stein is used.

    This change points at the most recently released stable/stein horizon
    (15.0.2) in the requirements.

    This change has no effect on build or deployment, only tox.

    The upper constraints zuul job overrides the stein upper constraints,
    and therefore the oslo concurrency 4.0.0 released Feb 3rd is no
    longer triggering a failed tox job.
