    Disable ceph-dashboard by default in Stein

    ceph-ansible 4 recently changed defaults and now
    deploys dashboard by default. This will cause a
    TripleO Stein deployment to fail unless additional
    parameters are added which Stein does not support.
    Opt to override this new ceph-ansible default in
    Stein (master, the future Train) will support it
    however.

    This patch is going directly into Stein instead of
    being added to master and then being backported,
    since master has a CephEnableDashboard parameter
    in addition to plenty of code to correctly set up
    the dashboard which would be too much to backport.
    Instead of misleading the user with a non-working
    CephEnableDashboard parameter, we just directly
    pass a flag to ceph-ansible to disable it.
