Version 6.2.3 enables on to configure edge resources. This patch ensures that no reservations will take place. This will also enable us in the future to expose this feature. The patch also adds in a utility that can be run out of band. This can be done if the NSX is upgraded to 6.2.3 and the plugin will not need to be restarted.
