### What?
Adds a new property to collection / global config `forceSelect` which
can be used to ensure that some fields are always selected, regardless
of the `select` query.
### Why?
This can be beneficial for hooks and access control, for example imagine
you need the value of `data.slug` in your hook.
With the following query it would be `undefined`:
`?select[title]=true`
Now, to solve this you can specify
```
forceSelect: {
slug: true
}
```
### How?
Every operation now merges the incoming `select` with
`collectionConfig.forceSelect`.
