.SYNOPSIS
    Synchronize Netbox Virtual Machines from VMware vCenter.

.DESCRIPTION
    The Sync-Netbox cmdlet uses the Django Swagger REST API included in Netbox and VMware PowerCLI to synchronize data
    from vCenter to Netbox.
    Function skeleton adapted from https://gist.github.com/9to5IT/9620683

.PARAMETER Token
    Netbox REST API token

    Author:         Joe Wegner <joe at jwegner dot io>
    Creation Date:  2018-02-08
    Purpose/Change: Initial script development
    License:        GPLv3

    Note that this script relies heavily on the PersistentID field in vCenter, as that will uniquely identify the VM
    You will need to create a vcenter_persistent_id custom field on your VM object in Netbox for this to work properly

    removed PowerCLI requires header due to loading error
