Feature Request: “Rate limit” Pushes to control user behavior.

I would like to make a PR to slowly release a push notification to users over a variable period of time.
Imaging a hot dog stand app that want to push out to nearby users “come buy a hot dog!”.

Current way: the push is sent out to everyone about the same time and there is a VERY long line at the hotdog stand and lost customers because the hot dog stand can’t handle the volume.

Describe the solution you'd like
the push is released to batches of users over an hour (or 2 hours) giving a steady stream of customers without overwhelming the stand.

On a technical level this could also be used to prevent traffic spikes to your app that can overwhelm servers and cause a poor user experience.

Describe alternatives you've considered

I’ve considered writing a cloud job that sends pushes over time but those jobs can’t be access or controlled from the dashboard and I think this feature could benefit the parse community.

Additional context
Add any other context or screenshots about the feature request here.

The issue names no files, tests, or entry points. Start by locating the existing push-notification flow and dashboard controls, then define how batches and a variable one- or two-hour release period should be configured and verified. Done means pushes can be released gradually without overwhelming users or servers.
