Title:
  [RFE] Adding Port Statistics to Neutron Metering Agent

Status in neutron:
  Won't Fix

Bug description:
  [Existing Implementation]
  Currently the Neutron Metering Agent only measures the bandwidth usage of the Routers. 

  [Proposal]
  The Neutron Metering Agent will be extended to also support Port statistics.

  {collisions=0, 
  rx_bytes=874, 
  rx_crc_err=0, 
  rx_dropped=0, 
  rx_errors=0, 
  rx_frame_err=0, 
  rx_over_err=0, 
  rx_packets=11, 
  tx_bytes=70, 
  tx_dropped=0, 
  tx_errors=0, 
  tx_packets=1}

  In this implemention, the support for Port statistics will be added
  using the OpenvSwitch tools.

  [Suggesting Initial Implementation]
  - Add method _notify_port_stats which collects ports statistics from ovsdb and sends the notification.
  - The method _notify_port_stats is called the from _metering_loop to keep sending the port statistics.

  Looking forward to feedbacks and suggestions.

  [Benefits]
  These metrics can further be exposed to Ceilometer and can be helpful for metering and monitoring purposes.
