Investigate schema relations bug in `Distribution` in `aws_cloudfront`

[L. Fernando De Pombo]

We are getting stopgap lazy loader issues here. It could be as simple as having an optional AWS field as not nullable, but could be something else

So I've been trying to reproduce and I've seen some issues but I have not been able to reproduce the main error that was during the sync apparently. Some of the small task and/or issues seen on my branch cf-dist:

• Try to replicate a failure syncing the distributions
• callerReference is set to nullable but it is not
• if you tried to create a distribution with an empty json for the mandatory fields it fails on creation. I think that should be handled properly in the mapper. or maybe a trigger? I need to understand better cf distributions.
• There's an issue with the revert logic :/ specifically for type json fields. The query generated is not setting the type properly. I think I've solved this for the get_sql_* RPCs but they do not use the same code. Maybe I should find a way to make them share as much as possible for this logic...
