Fastapi-users

This is a major release with lot of changes under the hood. Please review the [Migration documentation](https://frankie567.github.io/fastapi-users/migration/08_to_10/) carefully.

Breaking changes

* User id. and OAuth accounts id. are now real UUID instead of strings. This way, we can leverage the efficient storage and indexing of DBMS that support it (PostgreSQL and MongoDB).
* Routers are now splitted. You have to include all the ones you need, with control on the prefix and tags.

Bug fixes

* Fix 68 (at last!). Security schemes are now correctly discovered by the OpenAPI schema (even multiple ones!).

Improvements

* Bump dependencies:
* `email-validator ==1.1.0`

Breaking changes

* Remove the list users endpoint. It seemed to me that it was too opinionated ; and I prefer end-developer to implement it its own way with pagination, etc.
