[reSIProcate] Equivalent of InviteSession::InviteSessionEndCommand but for AppDialogSet::end() (for CANCEL)

[Francis Joanis <francis.joanis@xxxxxxxxx>]

Hi,

I want to asynchronously send a CANCEL from my application but I
couldn't find any pre-made DumCommand to do this. For example, there
is the InviteSessionEndCommand available, but it sends a BYE and not a
CANCEL.

I couldn't find anything that does that so far, so I'll probably be
adding a new one called InviteSessionTerminateCommand that will end up
calling InviteSessionHandler::terminate - or something like that.

Also, I know that I could create my own DumCommand to do this :), but
I feel like it might be missing from the API.

Any comments?

Thanks,
Francis
