VMWare NSXv: Metadata for distributed router

Browse Source 
Metadata support for NSXv distributed routers is provided via DHCP Edge
appliances. In order to avoid conflicts between distributed routers and
DHCP Edges which map different networks with same CIDRs, we create a 1:1
mapping between an distributed router and a DHCP Edge.

This patch contains the data model for the above, while the implementation
is in vmware-nsx repository.
