Enable a admin to configure a global search domain. That is, if a subnet is not created with a search domain (commit d9f3ee826acf3fc5a1c436361790940237ef9784) then is a domain is defined in the configuration file then we can use that one. In the nsxv section there will be a new variable - dns_search_domain Change-Id: I112a00dbc89b1c7702e82ecfa6ec974b7b9cce8d
