Add properties to the thread context map for logging

Desired Behavior

• For logging purposes (Log4j) a number of properties should be available to identify the source of logging.
• The Controller and Agent adds the following properties to the thread context map associated with the thread that generated the logging event

  • js7.serverId = "Controller:<controllerId>"|"Subagent:<subagentId>" 
    js7.clusterNodeId = "Primary"|"Backup"

• The value of js7.clusterNodeId is provided depending on the js7.journal.cluster.node.is-backup setting in the controller.conf file: true => "Primary", false => "Backup".
