[cloud] Create ECS integration test suite (#33757)

Tests for: * ecs_cluster * ecs_service * ecs_service_facts * ecs_taskdefinition * ecs_taskdefinition_facts * Add idempotency testing Test ecs_cluster, ecs_service and ecs_taskdefinition for trivial idempotency. Add FIXMEs to the tests because the latter two fail. Remove unused dependencies
