function Get-CCMProvisioningMode {
    <#
    .SYNOPSIS
        Get ConfigMgr client provisioning mode info
    .DESCRIPTION
        This function will allow you to get the configuration manager client provisioning mode info using CIM queries.
        You can provide an array of computer names, or cimsession, or you can pass them through the pipeline.
        It will return a pscustomobject detailing provisioning mode
    .PARAMETER CimSession
        Provides CimSessions to get provisioning mode for
    .PARAMETER ComputerName
        Provides computer names to get provisioning mode for
    .EXAMPLE
        C:\PS> Get-CCMProvisioningMode -Status Enabled
            Retrieves provisioning mode info from the local computer
    .EXAMPLE
        C:\PS> Get-CCMProvisioningMode -ComputerName 'Workstation1234','Workstation4321'
            Retrieves provisioning mode info from Workstation1234, and Workstation4321
