    Require that known-bad EC schemes be deprecated

    We said we were going to do it, we've had two releases saying we'd do
    it, we've even backported our saying it to Newton -- let's actually do
    it.

    Upgrade Consideration
    =====================

    Erasure-coded storage policies using isa_l_rs_vand and nparity >= 5 must
    be configured as deprecated, preventing any new containers from being
    created with such a policy. This configuration is known to harm data
    durability. Any data in such policies should be migrated to a new
    policy. See https://bugs.launchpad.net/swift/+bug/1639691 for more
    information.
