Kyle Mestery c3afb3147e Add an "IPv6 Impact" section to the template 
This change adds a requirement for an "IPv6 Impact" section. In the review for
Kilo priorities [1], the issue was raised around IPv6 being a priority. One
outcome was the thought to ensure new features are IPv6 ready from the start.
This change ensures specs have a section detailing how they affect IPv6.

I've also updated approved specs with what I perceive to be their IPv6
readiness. I hope the original authors can view these to confirm what I've
put in there.

OFAgent: Simplify bridge setup

https://blueprints.launchpad.net/neutron/+spec/ofagent-bridge-setup

Problem Description

  • ofagent uses bridge name (eg. "br-int") to specify the bridge to control. it's OVS-dependent.
  • ofagent automatically set up the bridge on startup. (i.e. add-br, set br protocols, set-controller, etc) there are little point to perform it every time an agent starts up. one-time setup during deployment is enough. also, it's OVS-dependent.

Proposed Change

  • use datapath-id instead of bridge name. introduce a new config option to specify the bridge using datapath-id. make it an alternative of "integration_bridge" option.
  • remove code to set up the bridge from ofagent. document the instruction to set up the bridge instead.
  • adapt devstack accordingly.
  • retire "integration_bridge" option for ofagent later. (probably in "L" cycle.)

Alternatives

instead of datapath-id, OFPMP_DESC might be usable to distinguish bridge. OVS by default doesn't provide useful description though.
