    Pushing this down into the ZooRunnable does have the potential for future programming
errors. Implementations could try to "be efficient" and call `getZooKeeper()` once and store
it as a member variable to the `ZooRunnable` implementation. This would negate the reconstruction
of the `ZooKeeper` instance that the `retry()` loop is doing.
    I think some javadoc explaining that `getZooKeeper()` could be used by the implementations
on the `abstract T run()` definition for future Accumulo devs would be very worthwhile.
