Pluging to monitor promises kept/not kept/repaired in cfengine 3.6

Nice way to see if your promises are idempotent, and if your machine is doing the right things
"autoconf" should be used to check for the presence of cfengine (or the logfile you refer to), and answer "yes" if present, and "no (cfengine not present)" if not.

It should always "exit 0".
