CancellationToken support

[thomaswurtz]

Hi,
Are there any plans for cancellation token support in the async API? I think this would be a nice addition.
One suggestion would be to add it as a new overloads to the async extension methods as other ORMs like NHibernate.

In case support is missing in underlying libraries an option can be to just use cancellationToken.ThrowIfCancellationRequested();

Thanks
Thomas
