<#
    .SYNOPSIS
        Invoke the SCDPBundleInstall.exe file
         
    .DESCRIPTION
        A cmdlet that wraps some of the cumbersome work of installing updates / hotfixes into a streamlined process
         
    .PARAMETER InstallOnly
        Instructs the cmdlet to only run the Install option and ignore any TFS / VSTS folders and source control in general
         
        Use it when testing an update on a local development machine (VM) / onebox
         
    .PARAMETER Command
        The command / job you want the cmdlet to execute
         
        Valid options are:
        Prepare
        Install
         
        Default value is "Prepare"
         
    .PARAMETER Path
        Path to the update package that you want to install into the environment
         
        The cmdlet only supports an already extracted ".axscdppkg" file
         
    .PARAMETER MetaDataDir
        The path to the meta data directory for the environment
         
        Default path is the same as the aos service PackagesLocalDirectory
         
    .PARAMETER TfsWorkspaceDir
        The path to the TFS Workspace directory that you want to work against
         
        Default path is the same as the aos service PackagesLocalDirectory
         
    .PARAMETER TfsUri
        The URI for the TFS Team Site / VSTS Portal that you want to work against
         
        Default URI is the one that is configured from inside Visual Studio
         
    .PARAMETER ShowModifiedFiles
        Switch to instruct the cmdlet to show all the modified files afterwards
         
    .PARAMETER ShowProgress
        Switch to instruct the cmdlet to output progress details while servicing the installation
         
    .EXAMPLE
        PS C:\> Invoke-D365SCDPBundleInstall -Path "c:\temp\HotfixPackageBundle.axscdppkg" -InstallOnly
         
        This will install the "HotfixPackageBundle.axscdppkg" into the default PackagesLocalDirectory location on the machine.
