Personally, I don't want to rewrite ZooCache, but I'm not going to argue against it either.
I also don't know anything about PathChildrenCache.

> ZooCache, likely in attempts to be resilient to network flakiness, will indefinitely
retry to connect to ZooKeeper.
> While this is fine for internal user (Tserver, Master), this has a nasty habit of causing
clients to hang forever trying to connect to something that doesn't exist.
> A simple fix might be to introduce a retry count to {{ZooCacheFactory}} which we can
set when creating a {{ZooCache}} in {{ZooKeeperInstance}}. Would need to consider the implications
of doing this.
