This change refactors the rule-specific methods in qos_plugin.py
in order to facilitate implementation of additional QoS rule types.
Further, with the recent merge of
https://review.openstack.org/#/c/292488/, which prevents primary
keys in Neutron's oslo.versioned objects from being updated, the
QoS plugin needed additional refactoring. This change implements a
generic method in Neutron's base objects to handle object updates
without updating the primary key. This method is then used in the
QoS plugin.
