Support Cancellation tokens in all stores natively

[SeanFarrow]

Whilst implementing the interfaces allowing users to store data (IClientStore etc), I found that there is a lack of consistency around how Cancellation tokens are supported and passed to methods. The IServerSideSessionStore interface allows a cancellation token parameter to be passed in, but other interfaces do not provide this functionality.

This means users cannot pass cancellation tokens down stream easily, without depending on something like the ICancellationTokenProvider interface.

Can we have full support for this across the interfacesl.

I'd be happy to do the work and sign a CLA if the Duende teams would accept this.

Thanks,
Sean.

Hi @SeanFarrow - thanks for weighing in! I'll refer to the open RFC we have here - https://github.com/orgs/DuendeSoftware/discussions/285
