Using Customer user_id Instead of an Auth0 Generated user_id

Can the UUID generated outside of Auth0 rather than an Auth0 generated user_id to create a new user using the management API?

Assuming: 

1. UUID will not change. 
2. UUID is unique across all users.

• Auth0 Generated user_id

The customers can create a user with their own `user_id` (e.g. a UUID) using the `POST /api/v2/users` endpoint of the management API.

As described in the Create a user document, the `POST /api/v2/users` endpoint accepts the `user_id` parameter in the payload.
Please note that the custom user_id must comply with a certain set of validation rules, but a valid UUID complies so it's okay to use UUID
