emitServerReady
Summary
Notifies the node-hmr parent that this child process is ready to serve requests.
Call this after the app server starts listening. After a restart, node-hmr waits for this
signal before publishing the browser server:update event, preventing clients from refreshing
against a server that is not ready yet.
