Bug Fix: Improve Health Status of .opendistro-job-scheduler-lock Index in Single Node Clusters

This pull request addresses an issue where the .opendistro-job-scheduler-lock index was showing a yellow health status in single node clusters. The problem was caused by the use of indexrequest default settings, which were not optimal for single node environments.

Changes:

• Modified the replica settings for the .opendistro-job-scheduler-lock index to:

  {
    "index.number_of_shards": 1,
    "index.auto_expand_replicas": "0-1"
  }
