Allow developers to implement custom username rules

Feature: Developers to be able to implement custom username rules (via regex or some kind of GUI).

Description: As a Auth0 user, it is currently too difficult to implement username rules to my liking, as the only customisation is the length.

Use-case: This is a common point in which different services differ, and it should be easily customisable for a better user experience. Current methods of using actions/rules/hooks are very unwelcoming.

This would also slightly improve the not-so-great username implementation.
