In the current state, doing async tasks by using the UserManager<> class. Actually, it's not possible to pass any CancellationToken as it is using the cancellation token stored in the class itself. The exact same issue appears in the SignInManager<>class.

Describe the solution you'd like

Update every methods of the UserManager class to add a CancellationToken parameters to pass trough in case of cancellation has been requested by the user.

Triage: This seems like an appropriate request. We probably want to provide CancellationToken as a method-level parameter and not class-level property. @TheYoxy Would you be interested in submitting an API proposal to add CancellationToken to the necessary async methods?

I can try to write it. If I have others remarks regarding these two classes, should I mention them too inside the API proposal? (There is no interface for IoC for these classes and there is some Async suffix that are missing on some methods)

We can split these out into separate issues for easier review. Thanks for taking a look at this!
