Missing cancellation support in the .NET API

[malthuis]

Expected behavior:

I can pass a CancellationToken into an async method call, for example:

CardPreAuthorizationDTO result = await mangoPayApiService.Api.CardPreAuthorizations.CreateAsync(preAuth, cancellationToken);

This should, if the call gets canceled, throw an OperationCanceledException

Actual behavior:

I cannot pass it and have to use:

CardPreAuthorizationDTO result = await mangoPayApiService.Api.CardPreAuthorizations.CreateAsync(preAuth);

Also this throws a TimeoutException after 1.5 seconds.

Also, the MangoPay production API seems to be very slow since a couple of days so there errors actually occur on a daily basis at the moment.

Could you please have a look at the performance issues and consider adding cancellation support?

Thanks in advance.
