Schema.prototype.omit() - just like Schema.prototype.pick(), but excludes keys rather than includes them

🚀 Feature Proposal

Schema.prototype.pick creates a clone of the original schema with a subset of the original schema's fields: https://mongoosejs.com/docs/api/schema.html#schema_Schema-pick, https://thecodebarbarian.com/whats-new-in-mongoose-58-schema-pick-and-better-stack-traces.html . It behaves like Lodash pick() for schemas.

We should also have a omit() method that behaves like Lodash's omit().

const schema = new Schema({ name: String, age: Number });
schema.omit(['age']); // Equivalent to `new Schema({ name: String })`
