.SYNOPSIS
This function will uninstall the LabTech agent from the machine.
.DESCRIPTION
This function will stop all the LabTech services. It will then download the current agent install MSI and issue an uninstall command.
It will then download and run Agent_Uninstall.exe from the LabTech server. It will then scrub any remaining file/registry/service data.
.PARAMETER Server
This is the URL to your LabTech server.
Example: https://lt.domain.com
This is used to download the uninstall utilities.
If no server is provided the uninstaller will use Get-LTServiceInfo to get the server address.
.PARAMETER Backup
This will run a 'New-LTServiceBackup' before uninstalling.
.PARAMETER Force
This will force operation on an agent detected as a probe.
.EXAMPLE
Uninstall-LTService
This will uninstall the LabTech agent using the server address in the registry.
.EXAMPLE
Uninstall-LTService -Server 'https://lt.domain.com'
This will uninstall the LabTech agent using the provided server URL to download the uninstallers.
