the class TestDefaultResourceAwareStrategy method testDefaultResourceAwareStrategyWithoutSettingAckerExecutors.

/**
 * test if the scheduling logic for the DefaultResourceAwareStrategy is correct
 * when topology.acker.executors.per.worker is set to different values.
 *
 * If {@link Config#TOPOLOGY_ACKER_EXECUTORS} is not set,
 * it will be calculated by Nimbus as (num of estimated worker * topology.acker.executors.per.worker).
 * In this test, {@link Config#TOPOLOGY_ACKER_EXECUTORS} is set to 2 (num of estimated workers based on topo resources usage)
 *
 * For different value for {@link Config#TOPOLOGY_RAS_ACKER_EXECUTORS_PER_WORKER}:
 * -1: Note we don't really set it to be -1.
 *     It is just a special case in this test that topology.acker.executors.per.worker is unset, nimbus will set to 1 by default.
 * 0:  Since {@link Config#TOPOLOGY_ACKER_EXECUTORS} is not set either, acking is disabled.
 * 1:  2 ackers in total. Distribute 1 acker per worker. With ackers being added, this topology will now need 3 workers.
 *     Then first two worker will get 1 acker and last worker get 0.
 * 2:  4 ackers in total. First two workers will get 2 acker per worker respectively.
