Don't sleep 30 minutes after final repetition in long-running

Prior to this commit, we were sleeping for 30 minutes after
every repetition of the agent requests in the long-running
simulation.  This sleep is not necessary after the final
repetition, and was adding 1-3 hours of unnecessary run time
to the jenkins jobs.  Getting rid of that last unnecessary
sleep should allow us to run through the jenkins jobs
much more quickly.

Fix broken long-running sims

The code for the long-running sims was broken.  There was a mutable
class variable that was being manipulated by multiple different
gatling "users" on the same instance of the class.

Also, Thread.sleep is a huge no-no in async code.  Now we're using
the gatling "pause".
