Information about the circuit breaker used to determine when a service deployment has failed.
The deployment circuit breaker is the rolling update mechanism that determines if the tasks reach a steady state. The deployment circuit breaker has an option that will automatically roll back a failed deployment to the last cpompleted service revision. For more information, see How the Amazon ECS deployment circuit breaker detects failures in the Amazon ECS Developer Guide.

threshold: int = ...
The threshhold which determines that the service deployment failed.
The deployment circuit breaker calculates the threshold value, and then uses the value to determine when to move the deployment to a FAILED state. The deployment circuit breaker has a minimum threshold of 3 and a maximum threshold of 200. and uses the values in the following formula to determine the deployment failure.
0.5 * desired task count
