This patch adds support for dns search domains in the nsx-v plugin.
DNS search domain is implemented as a string attribute extension to the
Subnet object.
Usage:
subnet-create net-name 10.0.0.0/24 --name subnet-name \
--dns-search-domain eng.vmware.com
subnet-update subnet-name --dns-search-domain new-domain.com
This commit adds a new table to store bindings for subnet attributes with
the necessary migration script.
