Description

Noticed in ACCUMULO-3858 that the number of ZK watchers was sometimes being reported larger than expected.

WatchTheWatchCountIT expected the watchers to be between 500 and 600, but, in debugging the test, I saw it sometimes above 600. Other times, it was happily in the expected range.

Need to investigate to make sure nothing fishy is going on and we have a good understanding of how many watchers we are setting.
