## Description
Adds `virtual` property to the fields config. Providing `true`
completely disables the field in the DB, which is useful for [Virtual
Fields](https://payloadcms.com/blog/learn-how-virtual-fields-can-help-solve-common-cms-challenges)
Disables abillity to query by a field with `virtual: true`.
Currently, they bloat the DB with unused tables / columns, which may as
well introduce additional joins.
