Code Issues Proposed changes

Add API extension for QoS minimum pps rule

Browse Source 
This patch implements support for CRUD operations for QoS minimum
packet rate, for example:

DELETE /qos/policies/$POLICY_ID/minimum_packet_rate_rules/$RULE_ID

Placement or dataplane enforcement is not implemented yet.

Any QoS driver can claim support for some QoS rule types

``supported_rules``, the QoS driver manager will recalculate rule types
dynamically that the QoS driver supports.
