Storage Schema doesn't use raw.properties

The fields here are using storage_schema.processed().X instead of storage_schema.raw().X so if you create a schema that looks like { raw:{exist_age_max:"1 week"}} it does nothing, you currently have to handle it via { raw:{}, processed:{exist_age_max:"1 week"}}
