Show Ivanti Environment Manager Configuration Details

<#
.SYNOPSIS

Show details of installed configurations for Ivanti UWM agents

.DETAILS

Works for both MSI installed configurations (either via Management Centre or other mechanisms) and native configurations

.PARAMETER

None

.CONTEXT

Computer

.NOTES

For native configurations, so those not installed via MSI, there are no details such as names of configurations held on the end-point

In the 2019.1 release, product configurations are no longer prefixd with "Ivanti xxx Manager Configuration" and thus they cannot be retrieved via name for non-native configurations
