Feature request: A way to set limitations to usage of specific resources (KV reads, writes, requests, etc.) in the dashboard, and being notified when these limits are approached.

### What problem are you trying to solve?

I feel like it is inevitable that mistakes will be made, either by me or others, that will cause a project to spend a lot of unnecessary resources. There is currently no way of setting a cap on resource usage, like KV reads and writes, and also no way of being notified when there is excessive spending.

### Describe the solution you'd like

I propose a dashboard feature that enables you to set limits on usage of specific resources for a specific project. I also think it would be very helpful to receive some sort of notification when these limits are being approached, and when they are actually hit. I think being notified by email makes the most sense.

### Describe alternatives you've considered

Right now, usage has to be manually monitored.
