* Changes the new Throughput Generators to track messages per window
instead of making per-second calculations which can have rounding errors.
Also, one of these had a calculation error which prompted this change in
the first place.
* Fixes a couple typos.
* Fixes an error where certain JSON fields were not exposed, causing the
workloads to not behave as intended.
* Fixes a bug where we use wait not in a loop, which exits too quickly.
* Adds additional constant payload generators.
* Fixes problems with an example spec.
* Fixes several off-by-one comparisons.

Move Trogdor out of tools and into its own gradle module. This allows us to minimize
the dependencies of the tools module. We still keep Trogdor in the CLASSPATH
created by kafka-run-class.sh.
