Use ZooKeeperClient.fromConfig in tests

To make the tests more like running the apps, use fromConfig in the
tests rather than directly creating a client from a string connection
description.  Note that since fromConfig requires TLS and the tests
don't use it, a temporary argument has been added to that method to
allow non-tls connections; it's only used within the test suite.

In future changes, we can configure the tests to use TLS connections,
remove the argument, and then move client instantiation into the
server classes themselves (which will remove additional differences
between test and production startup code).
