Description: Script that Calls out to IPAM to release address for the VM in the decommissioning request
Requirements: 
-VComamnder 6.1.4 or higher
-Powershell V4 or greater
-InfoBlox 8.1.2 or greater

Note:
Your Environment may require additional or diffrent logic depending on how InfoBlox has been configured. This Example assumes there is no overlapping subnets in IPAM

vCommander workflow Run Syntax:
powershell.exe c:\Scripts\InfoBlox\InfoBlox_releaseIP.ps1 -IPAddress "#{target.ipv4Addresses}"
