    Add support for QoS for LinuxBridge agent
    
    There is a new QoS extension driver for the linuxbridge agent
    being added. This driver provides support for QoS configuring
    on the linuxbridge agent.
    This patch introduces two new config options for Linuxbridge agent:
    kernel_hz - HZ value of host kernel,
    tbf_latency - value of latency in tbf qdisc to calculate size of queue.

Title:
  L2 CommontAgentLoop does not allow subscribing to push notifications
  queues

Status in neutron:
  Fix Released

Bug description:
  L2 agents which are using neutron.plugins.ml2.drivers.agent._common_agent.CommonAgentLoop as base class are initializing rpc_agent to consume from rpc before l2 extension manager will subscribe to proper queues. Due to that agent is not consuming notifications from such queus.
  As example of issue I can give QoS extension in linuxbridge agent (https://review.openstack.org/#/c/236210/29). Linuxbridge agent can't create queues "neutron-vo-QoSPolicy-1.0" so it can't consume notifications about QoS policy updates.
