Add availability zones for agents

Registered by IWAMOTO Toshihiro on 2014-12-08

Implement availability zones for the DHCP and L3 agents. Just like Nova and Cinder, this allows users to specify where the network services run, giving better fault isolation.

Whiteboard

Jan-12-2016(hichihara): Completed.

Dec-15-2015(armax): almost feature complete. Needs tests to merge and docs to be written. Some issues found and bugs being filed.

September-14 (mestery): Per discussion in the neutron meeting this week, the patches are too invasive to merge this late in the cycle. Thus, Mitaka it is!

September-8 (mestery): This one is getting some good reviews, still looking at RC1.

sept-1-2015(armax): no code hit trunk yet, unlikely it'll make L3 at this point. Optimistically moving to L-RC1
