Support stopping ECS services with the Daemon scheduling strategy

Attempting to stop services in an ECS cluster that used the daemon scheduling strategy throws an error. The logs are:
```
I, [2019-05-20T19:00:13.578661 #30810] INFO -- : Stopping ECS service my-service...
E, [2019-05-20T19:00:13.598088 #30810] ERROR -- : An exception occurred during stop operation against resource my-ecs-cluster
E, [2019-05-20T19:00:13.598134 #30810] ERROR -- : The daemon scheduling strategy does not support a desired count for services. Remove the desired count value and try again
```
The code that stops the ECS services needs to be aware of the different types of scheduling strategies and used the appropriate mechanism to stop the service for each.
