      Description

      Using the default Logging Configuration logging.properties supplied with swarm-plugin leads to a severe degradation in performance in combination with Clone Workspace SCM Plugin.

      As line 36 enables Logging of all messages by specifying Level ALL our Slaves were creating a very large amount of log data leading to 100% CPU Usage.

      Setting the log level to INFO (specified in line 35 but commented out) resolved the issue. We think this should be the default.

          please submit a PR. Defaulting to INFO is preferable IMHO
