Object Minting Utility for db-controller

This is an optimization idea.

Each of the actions have a moment like
```javascript
const id = new ObjectID().toHexString()
let generatorAgent = req.user[process.env.RERUM_AGENT_CLAIM] ?? "http://dev.rerum.io/agent/CANNOTBESTOPPED"
let context = req.body["@context"]?{"@context":req.body["@context"]}:{}
let provided = JSON.parse(JSON.stringify(req.body))
let rerumProp = {"__rerum":utils.configureRerumOptions(generatorAgent, provided, false, false)["__rerum"]}
delete provided["_rerum"]
delete provided["_id"]
delete provided["@id"]
delete provided["@context"]
let newObject = Object.assign(context, {"@id":process.env.RERUM_ID_PREFIX + id}, provided, rerumProp, {"_id":id})
```
where this code is ALMOST a direct C&P, but not quite so it will take a little focus and thought. This can probably be a utility function, JSON in - JSON Out with some strategic flags to make sure to support the slight differences between actions

Localiza los action handlers en db-controller que repiten la secuencia mostrada para crear objetos y compara sus pequeñas diferencias. Define a partir de esos usos la entrada JSON, la salida y los flags estratégicos de la utilidad; se considera terminado cuando la lógica repetida de creación de objetos está consolidada y cada action conserva su comportamiento requerido.
