      Description

      • Storage Plugins Handler service is used on the Drill start-up stage and it updates storage plugins configs from
        storage-plugins-override.conf file. If plugins configs are present in the persistence store - they are updated,
        otherwise bootstrap plugins are updated and the result configs are loaded to persistence store. If the enabled
        status is absent in the storage-plugins-override.conf file, the last plugin config enabled status persists.
      • 'drill.exec.storage.action_on_plugins_override_file' Boot option is added. This is the action, which should be
        performed on the storage-plugins-override.conf file after successful updating storage plugins configs.
        Possible values are: "none" (default), "rename" and "remove".
      • The "NULL" issue with updating Hive plugin config by REST is solved. But clients are still being instantiated for disabled
        plugins - DRILL-6412.
      • "org.honton.chas.hocon:jackson-dataformat-hocon" library is added for the proper deserializing HOCON conf file
      • additional refactoring: "com.typesafe:config" and "org.apache.commons:commons-lang3" are placed into DependencyManagement
        block with proper versions; correct properties for metrics in "drill-override-example.conf" are specified
