Feature Request: Omit specific fields from model to json-schema

[hongkongkiwi]

Hi there,

I'd like the option to omit some fields specifically when generating the schema.

Right now, my model contains an updatedAt field, it is compulsory, but I want to specifically exclude this from the schema as it's automatically generated from the database.

In this specific case, I know I can simply change the field to be optional, but I'd really like the option to omit specific fields, perhaps with a comment like some other validators do? Or something? That would give a little control over the json-schema without messing with the DB.

hmmm alternatively, perhaps it could be great to simply have a list of fields to exclude. Since you already have the exclude logic for relation fields and such, it could be nice simply to have a custom array of fields to exclude. In my case, that would also work and I think be a really useful feature, in this case I could add "updatedAt" and just ignore all references to that field.
