Used by activity workers, Task states using the callback

run pattern to report that the task identified by the taskToken failed.
For an execution with encryption enabled, Step Functions will encrypt the error and cause fields using the KMS key for the execution role.
A caller can mark a task as fail without using any KMS permissions in the execution
role if the caller provides a null value for both error and cause fields
because no data needs to be encrypted.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginSendTaskFailure and EndSendTaskFailure.
