HPCC-12335 Cosmetic change to stop messages, referencing current state

The changes were made so the state of each component could be clearly viewed without any extraneous information.  I also added some more verbose debugging messages.  Also cleaned up some redundant lines of code.
Does this mean we have lost the "Already started" message as well as cahnging the "Failed" to "ok"? If so, I'm not sure that is desirable
