Added to the dictionary of NRPE states with 'known' pending states (stop/start/restart) and updated tests.
Was not rebased on master for initial branch due to stale local copy, hence duplicate commits.
The comment describes the change and not the line of code, better to leave the comment and the description in the commit message. 

The comment makes sense in the context of the change but would be confusing out of context. The line creates CRITICAL status as well as WARNING which conflicts with the comment.
