* Add part 1 watch functionality. (squashed) * add funcs for service/endpoint fqdns * add endpoints watch * document exposed funcs * only send subset deltas * locking for watch map * tests and docs * add pod watch * remove debugs prints * feedback part 1 * add error reporting to proto * inform clients of server stop+errors * add grpc options param * use proper context * Review feedback: * Removed client (will move to another repo) * Use new log functions * Change watchChan to be for string not []string * Rework how k8s plugin stores watch tracking info to simplify * Normalize the qname on watch request * Add blank line back * Revert another spurious change * Fix tests * Add stop channel. Fix tests. Better docs for plugin interface. * fmt.Printf -> log.Warningf * Move from dnsserver to plugin/pkg/watch * gofmt * remove dead client watches * sate linter * linter omg
