* go changes to support nameservers_from * clear nameservers before giving to dsp. * work * work * nameserver updates. * remove unused * name.com stinks at NS records. * whitespace * removing web(belongs in own repo). First sketch of DSP vs NAMESERVER_FROM * add DEFAULTS to replace defaultDsps. * initial gcloud provider. Simple records work. * namedotcom can do subdomain ns records now. * fix for mx and txt * kill dsp acronym
