Public bug reported:

"The oslo.versionedobjects library can be used to define a data model
within a project independent of external APIs or database schema for the
purposes of providing upgrade compatibility across distributed
services."

However in Neutron QoS this library is used to micro version the
different QoS Rules which increments when a new QoS rule is added. This
seems counter intuitive as if the highest common version across
distributed services is less than any services version it will simply
not be available to call.

What these versioned objects should be used for is to validate that the
parameters of the versioned object match the parameters of the highest
common version of that object and add or remove uncommon parameters to
correctly version the object.
