Currently when a MiddleManager or Indexer is disabled via API, the state is stored only in-memory. If it is restarted, the disabled flag is cleared. This is not desirable; it should only be cleared by an operator explicitly re-enabling the server. This patch fixes it by saving the state to a file.

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.
