Script to rename devices

This script makes the devices displayName the same as the sysName. It can be easily modified to update any property for any other property, or appending.  We use a couple different variations of this script to keep our standard naming conventions consistent throughout LogicMonitor (and our CMDB).

Made for API v1, I have not looked at how this might be different/easier with v2.  Just sharing in case others find it useful.  

Script was adapted from a script example @Chengjie Zhu posted.
