Problem
Currently, the Cedar mapping info field names are confused with application resource attributes.
e.g. Type field in Cedar mapping info
We cannot make customers change their existing databases if they already use a column with that name.

Solution
Move Cedar mapping info fields into a json object like following
{ "cedar_entity_mapping": { "entity_type": "Jans::SecretDocument", "id": "some_id" }, "color": "red", "size": "small" }
