#
# Registers the WinRM endpoint for this instance of PowerShell.
#
# If the parameters '-PowerShellHome' were specified, it means that the script will be registering
# an instance of PowerShell from another instance of PowerShell.
#
# If no parameter is specified, it means that this instance of PowerShell is registering itself.
#
# Assumptions:
#     1. The CoreCLR and the PowerShell assemblies are side-by-side in $PSHOME
#     2. Plugins are registered by version number. Only one plugin can be automatically registered
#        per PowerShell version. However, multiple endpoints may be manually registered for a given
#        plugin.
