This parameter decides how to handle updating a Marathon application that has an active deployment.
If this is set to true
(checked), then a new deployment will be forced and the current deployment
canceled. If this is set to false
(unchecked), then this plugin will attempt to update the Marathon
application every couple of seconds until a timeout is reached. If the plugin is unable to successfully update
the application before the timeout is reached, then the job will be marked as failed.
More information can be found on the Marathon REST API documentation page.
