Filter mutations/queries logging with a custom function

### What do you want and why?

Ability to filter which logs will be printed in the console.

There is a lot of noise generated by queries such as `getCurrentUser`

### Possible implementation(s)

a function declared inside `blitz.config.js` that receives the message going to be logged and extra metadata when available.

### Additional context
I have thousands of logs like that that are not much useful, I would like to be able to disable them on
a per case basis
