Allow add plugin to main process scope ( not app.js scope ), without eject the project.

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

Say I have a plugin run a headless browser to scrawl things
It's better to be a singleton instance through the whole nodejs process scope, not the app scope( for each request ).

For now, I should eject the server.js and add the plugin in it.

Is it possible to add process based plugin without eject ?
