Context
Adds better support for using circuit breakers with the fargate service to prevent boot-loops in ecs.
Description
This change adds an option for enabling circuit breakers for the Fargate service. In addition to enabling a feature flag which stops the service from being replaced when using enabling circuit breakers when no deployment controller was previously defined.
Testing
The circuit breaker is toggled on for the tests being added to the snapshots.
Audience
Looks to be both CargoNet and Tomler at the moment, but might be beneficial for more teams in the future in addition to enabling the circuit breakers by default to prevent bootloops.
