Install-RMAzureVmCert
Function Install-WinRMAzureVmCert {
<#
.SYNOPSIS
Downloads and installs the certificate created or
initially uploaded during creation of a Windows based
Azure Virtual Machine.
.DESCRIPTION
Downloads and installs the certificate created (or uploaded)
during the creation of a Windows based Azure Virtual Machine.
Running this function obtains and installs the certificate into
your local machine certificate store. Writing to the localhost's
cert store requires PowerShell to run elevated. Once the
certificate is installed, you can connect to Azure VMs using SSL
to improve security.

.PARAMETER SubscriptionName
The name of the Azure subscription whose VMs you want to get
certificates from. Use quotes around subscription names
containing spaces.
.PARAMETER ServiceName
The name of the Azure cloud service the virtual machine is
deployed in.
.PARAMETER VmName
The name of the Azure virtual machine to install the
certificate for.
