Disables globally running trace flags on SQL Server instances
Turns off trace flags that are currently enabled globally across SQL Server instances using DBCC TRACEOFF.
Useful when you need to disable diagnostic trace flags that were enabled for troubleshooting or testing without requiring a restart.
Only affects flags currently running in memory - does not modify startup parameters or persistent trace flag settings.
Use Set-DbaStartupParameter to manage trace flags that persist after restarts.

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.
