Add custom lint checks

### Description

From the top of my head we could automatically detect the following potential problem that we point out in the PRs all the time:
* Using `withScope` instead of `configureScope`
* Adding `final` keywords everywhere (parameters, properties, etc.)
* Adding @Nullable/@NonNull annotation everywhere (parameters, properties, etc.)
* Catching `Throwable` instead of `Exception`, see #1806

There's probably more, so keep updating this issue when you got something in mind.
