#### How can we help?

Hi team,
I would like to tag a schema with some metadata that will be included in any validation result of that schema or its children schema.
Is this possible with the current state of Joi?

I think it is similar to `artifact` but also work for failed rule.

```js
const schema = Joi.object({
name: Joi.string().required(),
})
.schemaTag('special-tag')

const result = schema.validate(
{ gaga: 'gaga' }
)

console.log(result.details.map(detail => detail.schemaTag))) // ['special-tag']
```
