/**
* The Persistent Tasks Executors are responsible for executing restartable tasks that can survive disappearance of a
* coordinating and executor nodes.
* <p>
* In order to be resilient to node restarts, the persistent tasks are using the cluster state instead of a transport service to send
* requests and responses. The execution is done in six phases:
* <p>
* 1. The coordinating node sends an ordinary transport request to the master node to start a new persistent task. This task is handled
* by the {@link org.elasticsearch.xpack.core.persistent.PersistentTasksService}, which is using
* {@link org.elasticsearch.xpack.core.persistent.PersistentTasksClusterService} to update cluster state with the record about running
* persistent task.
* <p>
* 2. The master node updates the {@link org.elasticsearch.xpack.core.persistent.PersistentTasksCustomMetaData} in the cluster state to
* indicate that there is a new persistent task is running in the system.
* <p>
* 3. The {@link org.elasticsearch.xpack.core.persistent.PersistentTasksNodeService} running on every node in the cluster monitors changes
* in the cluster state and starts execution of all new tasks assigned to the node it is running on.
* <p>
* 4. If the task fails to start on the node, the {@link org.elasticsearch.xpack.core.persistent.PersistentTasksNodeService} uses the
* {@link org.elasticsearch.xpack.core.persistent.PersistentTasksCustomMetaData} to notify the
* {@link org.elasticsearch.xpack.core.persistent.PersistentTasksService}, which reassigns the action to another node in the cluster.
* <p>
* 5. If a task finishes successfully on the node and calls listener.onResponse(), the corresponding persistent action is removed from the
* cluster state unless removeOnCompletion flag for this task is set to false.
* <p>
* 6. The {@link org.elasticsearch.xpack.core.persistent.RemovePersistentTaskAction} action can be also used to remove the persistent task.
