Title: Job flow killer puts termination reason in lock file

The strings like `Terminated job flow * (*); was {idle|pending} for *, * to end of hour` are now part of the lock string in `s3://blah/locks/j-blah/n`. This should simplify debugging - we can just look inside the lock file instead of sending ourselves email spam.
