Review comment:
I tried writing a test where the Drillbits (inside ClusterFixture) are setup
with ZK_APPLY_SECURE_ACL=false (to avoid the need to setup a secure ZK server
within the unit test) and the ClientFixture is setup with
ZK_APPLY_SECURE_ACL=true (to simulate the failure). Starting a test with
different values for the same property turns out to be quite hard because the
ClusterFixture internally instantiates a ClientFixure. Changing this behavior
might affect other tests.
