Feature request: Manage project's alerts via API

We have many (more than 20) projects in our team. As we’re experimenting with the best alerts setup for us, It would be really useful to be able to manage our project’s alerts settings via an API endpoint.

Take a look at what the API requests are in Chrome when doing it - almost everything our UI does, whether documented or not, you can do with the API (given Sentry’s UI is mostly an SPA).
