New-Password generates a password, randomly, of length $Length, containing
only alphanumeric characters, underscore, and dash.

.SYNOPSIS
Waits for the shutdown of the specified resource.

.DESCRIPTION
Wait-Shutdown takes a VM, and checks if there's a 'PowerState/stopped'
code; if there is, it returns. If there isn't, it waits ten seconds and
tries again.

.PARAMETER ResourceGroupName
The name of the resource group to look up the VM in.

.PARAMETER Name
The name of the virtual machine to wait on.
