NSX|V: add configuration variable for dns_search_domain

Browse Source 
Enable a admin to configure a global search domain. That is, if a
subnet is not created with a search domain (commit
d9f3ee826a) 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
