API: Usage metrics of which models are accessed most

[ryscheng]

What is it?

Describe the feature you'd like to request

In order to know which models to deprecate, we need to know how much we use each model. I think we should start with measuring against the API for now, since it'll be hard to do anything with the data exports.

Describe the solution you'd like

Hasura has built-in observability tooling https://hasura.io/docs/latest/observability/overview/

It'd be nice to use something like Segment, where we can identify the user and add event metadata.

Describe alternatives you've considered

• Maybe something built-into Hasura if there's built-in facilities
• Maybe monitor SQL queries
