    <#
     .SYNOPSIS
       Get basic ESXi host information
     .DESCRIPTION
       Will get inventory information for a vSphere Cluster, Datacenter or individual ESXi host
       The following is gathered:
       Hostname, Management IP, RAC IP, ESXi Version information, Hardware information
       and Host configuration
     .NOTES
       File Name : Get-ESXInventory.ps1
       Author : Edgar Sanchez - @edmsanchez13
       Contributor : Ariel Sanchez - @arielsanchezmor
       Version : 2.4.3
     .Link
       https://github.com/arielsanchezmora/vDocumentation
     .INPUTS
       No inputs required
     .OUTPUTS
       CSV file
       Excel file
     .PARAMETER esxi
       The name(s) of the vSphere ESXi Host(s)
     .EXAMPLE
       Get-ESXInventory -esxi devvm001.lab.local
     .PARAMETER cluster
       The name(s) of the vSphere Cluster(s)
     .EXAMPLE
       Get-ESXInventory -cluster production-cluster
     .PARAMETER datacenter
       The name(s) of the vSphere Virtual Datacenter(s).
     .EXAMPLE
       Get-ESXInventory -datacenter vDC001
       Get-ESXInventory -datacenter "all vdc" will gather all hosts in vCenter(s). This is the default if no Parameter (-esxi, -cluster, or -datacenter) is specified.
     .PARAMETER ExportCSV
       Switch to export all data to CSV file. File is saved to the current user directory from where the script was executed. Use -folderPath parameter to specify a alternate location
     .EXAMPLE
       Get-ESXInventory -cluster production-cluster -ExportCSV
     .PARAMETER ExportExcel
       Switch to export all data to Excel file (No need to have Excel Installed). This relies on ImportExcel Module to be installed.
       ImportExcel Module can be installed directly from the PowerShell Gallery. See https://github.com/dfinke/ImportExcel for more information
       File is saved to the current user directory from where the script was executed. Use -folderPath parameter to specify a alternate location
     .EXAMPLE
       Get-ESXInventory -cluster production-cluster -ExportExcel
     .PARAMETER Hardware
       Switch to get Hardware inventory
     .EXAMPLE
       Get-ESXInventory -cluster production-cluster -Hardware
     .PARAMETER Configuration
       Switch to get system configuration details
     .EXAMPLE
       Get-ESXInventory -cluster production-cluster -Configuration
     .PARAMETER folderPath
       Specify an alternate folder path where the exported data should be saved.
     .EXAMPLE
       Get-ESXInventory -cluster production-cluster -ExportExcel -folderPath C:\temp
     .PARAMETER PassThru
       Switch to return object to command line
     .EXAMPLE
       Get-ESXInventory -esxi 192.168.1.100 -Hardware -PassThru
