Option not to accept registration requests with occupied identity

Description

Currently when a registration request is submitted it is accepted even if using an identity which is already used. This request can be successfully accepted only if the existing user is removed before request is processed, what is very unlikely.

On the other hand the current behaviour prevents from scanning the system for used usernames.

The requested feature is to be able to turn on validation of whether identity is free at the submission stage.
