ExecutePolicyResponse has requireNonNull for 'status' but is not returned by ES when wait_for_completion=false

Elasticsearch Version

7.17, 8.3.3

Problem description

ExecutePolicyResponse describes status as a required field but if ?wait_for_completion=false is used it is not returned. Additionally task is returned and not taskId which means this is also not available even when ApiTypeHelper#DANGEROUS_disableRequiredPropertiesCheck(false) is used.

without wait for ?wait_for_completion=false

{
  "status": {
    "phase": "COMPLETE"
  }
}

with ?wait_for_completion=false

{
  "task": "XbmXqhlgRBqy_4Yx6xPKqw:1854616"
}

We can add Status.batches for tasks.get(..)
