v0.20.33

Request for activity cancellation should include scheduleId (#29)

Currently client passes activityId when requesting cancellation of
activity.  We instead want to include scheduleId as it makes
scanning for completed event simpler.
Once I consume this change on the server will completely remove
activityId from decision for request cancel activity completion
and also remove request cancel activity failed event as we need to
instead fail the entire decision.

v0.20.31

Use Payload for SA, Memo, and Headers (#28)
