Adds the following to CancelableRequestConsumer:

GetClientDataForCurrentRequest: The particular use case I need this
for is that I'm using the same CancelableRequestConsumer for multiple
sources so that I don't know whic CancelableRequestProvider to pass in
to GetClientData. None-the-less it seems a lot easier to use this when
always get the provider and handle.

GetFirstHandleForClientData: For this one I know I want to cancel a
request for a given client data but don't know the associated handle.

BUG=none
TEST=none
