When you delete a service, if there are still running tasks that require
cleanup, the service status moves from ACTIVE to DRAINING, and the
service is no longer visible in the console or in the ListServices API
operation. After the tasks have stopped, then the service status moves
from DRAINING to INACTIVE. Services in the DRAINING or INACTIVE
status can still be viewed with the DescribeServices API operation.
However, in the future, INACTIVE services may be cleaned up and purged
from Amazon ECS record keeping, and DescribeServices calls on those
services return a ServiceNotFoundException error.
If you attempt to create a new service with the same name as an existing
service in either ACTIVE or DRAINING status, you receive an error.
