workerthreads setting no longer has any affect

[bdw429s]

The --worker-threads 150 setting does nothing now. It used to work in the version of Runwar/undertow we had in CommandBox 3.x but I noticed this week that I tried to use that setting while doing performance testing on CommandBox 4, and no more than 30 CF requests would process at a time regardless of what I set the worker threads setting to. Perhaps Undertow changed how they accept that setting?
