Add object versioning to QoS DSCP.

- Changes RULE_TYPE_DSCP_MARK to RULE_TYPE_DSCP_MARKING to conform
  with the rules name.
- Added object versioning to qos related objects.
 - qos/rule: Throws a QosRuleVersionUnavailable exception when
   the QosDscpMarkingRule version is < '1.1'.
- removed test object version incrementation TODO from test_policy.py
 - Object versioning can not be used to increment the object version.
