feat(ecs): Add support for ECS deployment circuit breaker

[jgrumboe]

This is my first contribution, and I tried to implement spinnaker/spinnaker#6225

This change comes together with this PR from clouddriver: spinnaker/clouddriver#6132

It implements a new checkbox to activate ECS Deployment Circuit Breaker for the ECS service; the default is false to not change any existing behavior.

The checkbox looks like this. I thought it should go under "Advanced settings".

If enabled, it adds the attribute enabledDeploymentCircuitBreaker to the server group:

Running the Deploy stage will create an ECS service with Deployment Circuit Breaker enabled:

I'm open for your comments and your thoughts, also on the implementation - I mainly "mimicked" how other attributes/feature were implemented and tried my best "copy/pasting". 😏

LGTM. I would switch between the checkbox and the text to have the same experience as for the other fields but it looks ok.

Good point. I copied it from somewhere.
I will switch it. So the checkbox should be aligned with the text input boxes above, right?

Yes, I think it would look better 👍

It looks like this now, much cleaner.
