Usage monitoring of requests and data

### What problem are you trying to solve?

I want to have insight in how many requests and data I use over all my Deno Deploy projects.
I am currently on the free plan, but I would like to know if/when I should move to the pro plan.

### Describe the solution you'd like

I would like a page in Deno Deploy where I can see how many requests and data I used this billing period.
I want the usage of all my Deno Deploy projects *aggregated* in this page.

### Describe alternatives you've considered

It is probably possible to get the a feel of my usage by looking at the analytics of every project, and summing them up.

This is however not very accurate because the graph doesn't show the billing period.

Also, I have to sum the usages of the individual project manually, which is not very convenient.
