function Get-DbaServerTrigger {
    <#
.SYNOPSIS
Get all existing server triggers on one or more SQL instances.
 
.DESCRIPTION
Get all existing server triggers on one or more SQL instances.
 
.PARAMETER SqlInstance
The SQL Instance that you're connecting to.
 
.PARAMETER SqlCredential
SqlCredential object used to connect to the SQL Server as a different user.
 
.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.
