(This is some clean-up work that I need to do in order to wrap up the maintenance mutex project.)

In rolling out the maintenance mutex, I created two versions of the puppet wrapper script: one version that checked for (and subsequently used) mmutex, and another that didn't.

Along the way, I verified that the former version didn't use mmutex if it wasn't deployed to the machine.

Now that we're confident that this works, we want to make sure that we don't have two versions of the puppet wrapper script to maintain forever after. I need to replace the wrapper script that doesn't check for mmutex with the wrapper script that does and delete any logic that switches between the two.
