PR apache#19368 updated the enabled/disabled state of an MM or Indexer to persist across restarts. In some cases, such as disabling a server before doing an in-place restart, it is more convenient to automatically re-enable on restart. This patch adds a config parameter to restore the old behavior: druid.worker.startAlwaysEnabled.

PR #19368 updated the enabled/disabled state of an MM or Indexer to persist across restarts. In some cases, such as disabling a server before doing an in-place restart, it is more convenient to automatically re-enable on restart.
This patch adds a config parameter to restore the old behavior:
druid.worker.startAlwaysEnabled.Release note: MiddleManagers and Indexers now persist their enabled or disabled state across restarts. If you prefer the old behavior, where the server re-enables itself after a restart, set
druid.worker.startAlwaysEnabled = true.
