Controls to disable eager loading

I have some situations where I'm loading an included resource that lives in a different DB than the primary resource being loaded. AR.includes as it is called in Resource.apply_includes method breaks it. I am avoiding this by overriding apply_includes to skip eager loading for certain resource names, but I have a distaste for overriding more methods than I need to out of concern for long term brittleness of my codebase.

I'd like to add this option to resource associations eager_load: false. Anyone have initial feedback?

Start with Resource.apply_includes and the AR.includes call described in the issue, then inspect how resource associations are defined and processed. Determine the behavior needed for an eager_load: false association and identify or add coverage for resources backed by different databases; done means those associations no longer trigger eager loading while other includes retain their behavior.
