function Get-DbaRgWorkloadGroup {
<#
.SYNOPSIS
Gets all Resource Governor Pool objects, including both internal and external
 
.DESCRIPTION
Gets all Resource Governor Pool objects, including both internal and external
 
.PARAMETER SqlInstance
The target SQL Server instance(s)
 
.PARAMETER SqlCredential
Allows you to login to SQL Server using alternative credentials
 
.PARAMETER InputObject
Allows input to be piped from Get-DbaRgResourcePool
 
.PARAMETER EnableException
By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
