Tim Burke 2c3ac543f4 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.
