RolloutService

Cancel a rollout

Cancels a running, pausing, paused, system-paused, or stabilizing rollout by freezing the current traffic split. Revert is removed and rejected; cancel with freeze, then run a reverse rollout back to the source. The response is the accepted rollout snapshot; poll GetRollout until it reaches CANCELED.
