Get MAC Address to Portgroup Name Mapping of vCenter VM

getMACAddressToPortGroupNameMapping.js

// VMware vRealize Orchestrator action sample.  Valid for vRA/vRO 7.0+

// Action Inputs:
// cluster    VC:ClusterComputeResource    
// vm         VC:VirtualMachine
//
// Action Output:
//	return type: Properties
//  MAC Address returned from vCenter has "-" which is replaced by ":" as in Windows OS
